Psychological and social predictors of changes in fruit and vegetable consumption over 12 months following behavioral and nutrition education counseling.

This study assessed psychological and social factors predicting 12-month changes in fruit and vegetable consumption achieved by 271 men and women from a low-income population randomized to brief behavioral and nutrition education counseling. Greater increases in fruit and vegetable intake were achieved in the behavioral than in the nutrition education condition (1.49 vs. 0.87 portions per day, p=.021). Increases were predicted by baseline social support for dietary change but not by baseline psychological measures. However, short-term (8-week) changes in dietary self-efficacy, encouragement, anticipated regret, perceived benefits, and knowledge of recommended intake predicted 12-month changes in fruit and vegetable consumption independently of gender, age, ethnicity, income, and baseline intake. These factors accounted for 51% of the superiority of behavioral counseling over nutrition education.     

Diet, exercise, and physical discomfort in college students

778 students in a 4-yr. urban commuter college were tested to determine the effects of exercise and diet on self-reported discomfort. High exercisers reported significantly less physical discomfort than moderate or low exercisers. Greater consumption of sweets and fast food were significantly related to reported physical discomfort regardless of levels of exercise. High levels of fruit and vegetable consumption were associated with less discomfort in high exercisers. High dairy consumption was significantly related to fewer symptoms for high exercisers. Men who reported high ingestion of caffeine had significantly more discomfort than those who reported moderate to lower ingestion of caffeine.     

Increasing Positive Health Behaviors in Adolescents with Nutritional Goals and Exercise

Research has documented that low-income urban youth are at risk for obesity and related health problems. Our goal was to develop a brief, developmentally informed intervention to increase positive health behaviors (e.g., diet and exercise) among low-income, minority adolescents. Our study was designed to examine the feasibility and potential impact of our single session intervention that was delivered in a primary care setting. The participants were 100 adolescents from an urban adolescent medicine clinic who were randomly assigned to one of two conditions: a) a 3–5?min goal-only session or b) a 15–20?min motivationally enhanced intervention. Health behaviors and individual characteristics (i.e., autonomous motivation, self-efficacy) were assessed at baseline and re-assessed at follow-up 1 month later with 53?% of the youth completing the follow-up assessment. Those in the enhanced intervention group were more likely to participate in the follow-up as were those who reported higher baseline motivation and self-efficacy. Both groups reported statistically significant health behavior improvements over time and older adolescents reported more improvements. The two conditions did not significantly differ in reported health improvements. Self-efficacy predicted improvements in self-reported fruit and vegetable intake at follow-up. Results support that a brief “chat” with adolescents about their personal goals and values appears to have the potential to increase their positive health behaviors and appears to be useful as a preparatory intervention for weight management efforts for urban teens. The study demonstrates the feasibility and potential efficacy of implementing this 20?min intervention into primary care settings, thereby helping urban youth focus on their individualized goals, values, and motivations for health.     

Controlling anger in self-reported sober and alcohol intoxicated states: moderating effects of trait anger and alcohol consumption

Controlling anger in self-reported sober and alcohol intoxicated states: Moderating effects of trait anger and alcohol consumption. Scandinavian Journal of Psychology 52, 382-388. Retrospective self-reports about prior sober and alcohol intoxicated states were explored to reveal moderating effects of trait anger and alcohol consumption on anger control. The analyses were based on self-reports of trait anger and alcohol consumption as well as self-reports of the participants' typical levels of anger control in sober and alcohol intoxicated states in a population based sample of Finnish twins and their siblings (N = 4,852). The reported levels of anger control were lower regarding prior alcohol intoxicated states than sober states. A three-way interaction between alcohol consumption, trait anger and anger control was found. Whereas no interaction between alcohol consumption and trait anger was found in the self-reported sober state, there was an interactive effect of trait anger and alcohol consumption on anger control in the intoxicated state, indicating that the difference in anger control between those with high levels of alcohol consumption and those with low levels, was greater at higher levels of trait anger. Women had lower levels of anger control than men, but the relationship between trait anger, alcohol consumption and anger control was similar for both genders. In conclusion, the results showed that those with high levels of trait anger and alcohol consumption showed the lowest levels of anger control in self-reported alcohol intoxicated states, and indicate the importance of separating between anger control when sober and intoxicated since anger control seems to be differently related to at least trait anger and alcohol consumption in these states.     

Antenatal determinants of early childhood talking delay and behavioural difficulties

The determinants of talking delay alone or its comorbidity with behavioural difficulties was examined in 5768 two-year-old members of the Growing Up in New Zealand longitudinal study. Using the MacArthur-Bates Communicative Development inventories and the total difficulties score from the preschool Strengths and Difficulties Questionnaire, a composite measure was created so that children were categorised as showing no language or behavioural concerns (72.5%), behavioural only difficulties (6.1%), language only difficulties (18.1%), and comorbid language and behavioural difficulties (3.3%). Analyses revealed that antenatal factors such as maternal perceived stress, inadequate folate intake, vitamin intake, alcohol consumption during the first trimester and maternal smoking all had a significant effect on child outcomes. In particular, low multivitamin intake and perceived stress during pregnancy were associated with coexisting language and behavioural difficulties. These findings support international research in showing that maternal factors during pregnancy are associated with developmental outcomes in the early childhood period, and demonstrate these associations within a NZ context. Interventions which address maternal stress management and health behaviours during pregnancy could be beneficial to offspring development.     

Association of hypertension-related distress with lack of self-care among hypertensive patients

Research on factors associated with poor adherence to self-care focuses primarily on psychiatric emotional disorders such as depression and anxiety, whereas non-psychiatric chronic-disease-related emotional distress has received little attention in hypertensive patients. The objective of this study was to evaluate the association of hypertension-related distress with the lack of self-care including low adherence to pharmacological treatment, lack of regular physical activity, low intake of fruits and vegetables and frequent intake of high-salt foods. A cross-sectional survey was conducted in 2014 in two family medical units affiliated with the Mexican Institute of Social Security. The study included 487 hypertensive patients >19 years of age. The conceptual framework for the study was based on the Health Promotion Model. The analysis included multiple Poisson regression models. We found that 21.1% of participants had hypertension-related distress. Low adherence to pharmacological treatment was identified in 45.8% of patients, whereas 46.8% lacked regular physical activity, 30.8% reported a low consumption of fruits and vegetables, and 54.6% frequently consumed foods high in salt content. Hypertension-related distress was associated with lack of regular physical activity and low intake of fruits and vegetables. These findings highlight the importance of addressing distress in order to improve self-care of hypertensive patients.     

Exploring the relationship between the Five-Factor Model of personality,social factors and self-reported delinquency

The ‘Big Five’ is one of the predominant models of personality structure but relatively little research has focussed on how the five factors might be related to self reported offending separately for males and females. This is problematic for understanding the relationship between personality and offending as females and males typically have different personality profiles and differ considerably in self-reported offending. In this research 720 adolescents (376 males and 344 females) completed a Big Five personality measure along with measures of self-reported offending, socioeconomic status and family structure. The results suggested that low agreeableness and low conscientiousness were independently related to the prevalence of self-reported offending for males and that low agreeableness was independently related to frequent male offending. Low conscientiousness was independently related to female offending, but so too were interactions between disrupted family and extraversion and disrupted family and openness. The interaction between extraversion and a disrupted family was also independently related to frequent female offending. Limitations and directions for future research are discussed.     

Sociodemographic and psychological predictors of changes in dietary fat consumption in adults with high blood cholesterol following counseling in primary care.

The associations between sociodemographic variables, psychological factors, and changes in dietary fat consumption over 4 months were assessed in a randomized controlled trial of behavioral counseling versus standard advice. Patients were 141 men and 150 women, with an average age of 52.1 years and total cholesterol level of 7.27 mmol/l (278 mg/dl). Smokers, younger patients, and those with greater body mass index had higher fat intake at baseline. Behavioral counseling led to greater reductions in fat intake than did standard advice. Self-efficacy and ratings of benefits of low-fat diets were related to fat consumption at baseline, and changes in these measures were correlated with changes in fat intake. Family support, baseline anticipated regret, and (for the behavioral counseling group only) baseline behavioral intentions predicted reductions in fat intake. The results indicated that psychosocial variables associated cross-sectionally with fat consumption do not necessarily predict change and that factors involved in the process of change and the prediction of change need to be differentiated.     

Gender differences in early risk factors for adolescent depression among low-income urban children

One component of a model by Nolen-Hoeksema and Girgus, who propose that risk factors for adolescent depression are more common in girls than in boys during childhood, was tested with 85 low-income, urban, African American and Latino kindergarten through fourth grade children who completed inventories of depression, stress, attributional style, gender role, and body image. Endorsing two of three predicted risk factors, girls reported slightly poorer body image and identified more strongly with a feminine gender role. Boys, however, reported a more negative attributional style. Feminine gender role was not associated with body image or negative attributional style. The applicability of the proposed model to a low-income, ethnic minority, urban population is discussed.     

Characteristics of older cyclists (65+) and factors associated with self-reported cycling accidents in the Netherlands

Cycling supports the mobility, health and independency of the ageing population. However, older cyclists have an increased injury risk. On average, the risk of older people to sustain an injury in a cycling accident is three times higher per cycling kilometre than for middle-aged people and the injury risk increases with age. In comparison with middle-aged cyclists (<65 years), the risk of hospitalization is more than four times as high for older cyclists (≥65 years). The aim of this study was to reveal characteristics of older cyclists in general and to explore which of these characteristics are associated with self-reported cycling accidents from age 59. More than eight hundred older cyclists (>65 years) filled out a questionnaire, which included questions on demographics, bicycle specifications and personal characteristics. By means of a logistic regression, the relationship between personal factors and self-reported bicycle falls were studied. The univariate models showed that age, physical and mental impairments, bicycle model, living environment, feelings of uncertainty of the cyclist and changed cycling behaviour (such as more patience, lower speed) were related to falling off a bicycle. From the multivariate model we can conclude that several factors are associated with falling off a bicycle in the older population: (1) every year the cyclists becomes one year older (from the age of 65), the chance they have fallen increases with 7.3%, (2) If cyclists have mental impairments, the chance they have fallen increases with a factor 2.5, (3) if cyclists were less than completely confident the chance they have fallen increases with factor 1.8, (4) if cyclists live in a rural environment compared to an urban environment the chance they have fallen increases with a factor 2.1. In conclusion, demographic, cycling and personal factors can be related to increased self-reported fall risk. It is advised to take these factors into account when implementing new cycling related safety measures.     

Disability,poverty, and other risk factors associated with involvement in bullying behaviors

Using a stigma-based bullying framework, the current study investigated how (a) disability status was related to bullying-related behaviors when controlling for gender, grade level, and free or reduced lunch status; (b) gender, grade level, and free or reduced lunch status moderated the associations of disability status with bullying-related behaviors; and (c) classification in specific disability categories was associated with bullying-related behaviors with a sample of 10,483 students (47.8% female) in elementary, middle, and high school. School records data were collected on grade level, gender, free or reduced lunch price status, disability status, and disability category. Students completed the Bullying Participant Behaviors Questionnaire (BPBQ), rating five types of bully role behaviors (bullying behavior, assistant behavior, victimization, defending behavior, and outsider behavior). Findings indicated that having a disability was associated with increased victimization, assisting, and defending behavior. Furthermore, disability status interacted in meaningful ways with several demographic factors: (a) females with a disability reported more victimization and reported engaging in more outsider behaviors than females without a disability, (b) elementary students with a disability reported more assisting and less defending behaviors than those without a disability, (c) high school students with a disability reported less bullying and assisting behaviors and more defending behaviors than those without a disability, and (d) students with a disability from low socioeconomic backgrounds reported more bullying and outsider behaviors than students not from lower socioeconomic family backgrounds. When comparing students from specific disability categories to those with no disability, students with an emotional disability reported more assisting, victimization, and outsider behaviors; students with other health impairment reported more assisting, victimization, and defending; students with autism reported less defending and outsider behaviors; and students with a learning disability reported more defending behavior. Exploratory analyses of the effects of school-level factors found that school size (enrollment) was positively related to prevalence of assisting and outsider behavior. The percentage of low-income students in a school was positively associated with the extent of victimization and defending behaviors reported, but negatively associated with the extent of outsider behaviors reported.     

Differences in psychosocial factors and fat consumption between stages of change for fat reduction

Abstract

Differences in fat consumption and psychosocial factors between subjects in different trans-theoretical stages of change for fat reduction were studied. Data on fat consumption, self-rated fat intake, attitudes, social support and self-efficacy were collected among a sample of 507 adults. Analysis of variance with Scheffe's multiple-comparison test was used to study differences in these factors between stages of change. Attitudes and social support were most positive among subjects in preparation and action. Self-efficacy expectations were lowest among subjects in contemplation and preparation. Fat consumption was highest among precontemplators hut no substantial differences between other stages were found. It is concluded that subjects in different stages of change differ in psychosocial factors that are regarded as important determinants of behavioral change. Based on these differences it is recommended to develop stage-tailored nutrition education. A majority of subjects in maintenance consumed more fat than is recommended. Therefore, it is suggested that the usually applied staging algorithms might need adjustment for a valid application in nutrition research.     

Protective Factors and the Development of Resilience in the Context of Neighborhood Disadvantage

The purpose of the present study was to examine relations among multiple child and family protective factors, neighborhood disadvantage, and positive social adjustment in a sample of 226 urban, low SES boys followed from infancy to early adolescence. The results indicated that child IQ, nurturant parenting, and parent-child relationship quality, measured in early childhood, were all significantly associated with a composite measure tapping low levels of antisocial behavior and high levels of social skills at ages 11 and 12. Parental romantic partner relationship quality (RPRQ) was only significantly related to positive social adjustment in the context of low levels of neighborhood disadvantage. Results suggest that with the exception of RPRQ, these protective factors operate in a comparable manner with respect to positive social adjustment for this predominantly low-income urban sample of boys.     

Age and food preferences influence dietary intakes of breast care patients.

Identifying major influences on food choice is an important component of nutrition intervention research. Sensitivity to the bitter taste of 6-n-propylthiouracil (PROP) and self-reported preferences for meats, fats, vegetables, and fruit were examined in 329 female breast care patients. Intakes of fat, saturated fat, fiber, folate, and vitamin C, established using 4-day food diaries, were the chief health outcome variables. The strongest predictor of food preferences was age. Preferences were linked to food intakes. Older women consumed less energy and saturated fat and more dietary fiber and vitamin C than did younger women. Age-related decline in taste sensitivity to PROP was associated with increased liking for bitter cruciferous vegetables. Age-associated changes in food preferences and eating habits have implications for the dietary approach to cancer prevention and control.     

Conscientiousness and fruit and vegetable consumption: exploring behavioural intention as a mediator

Clear associations have emerged between conscientiousness and health behaviours, such that higher levels of conscientiousness are predictive of beneficial health behaviours. This study investigated the conscientiousness-fruit and vegetable consumption relationship and whether behavioural intention mediated this relationship. A large sample of adults (N = 2136) completed an online battery of questionnaires measuring conscientiousness, behavioural intentions to consume fruit and vegetables, together with self-reported behaviour. Correlation analysis revealed that conscientiousness and each of its facets were positively associated with behavioural intention and self-reported behaviour. Hierarchical multiple regression analyses revealed that after controlling for age, gender and education, total conscientiousness, and the facets of responsibility, industriousness, order and virtue predicted self-reported behaviour. Further analysis revealed that in line with the Theory of Planned Behaviour, behavioural intention fully mediated the conscientiousness-fruit and vegetable behaviour relationship. In conclusion, low levels of conscientiousness were found to be associated with lower fruit and vegetable intentions, with the latter also associated with fruit and vegetable consumption.     

Interpersonal factors and perinatal depressive symptomatology in a low-income Latina sample

Interpersonal factors are among the risk factors that predispose women to experiencing mood disturbances during the childbearing years. This study investigates the trajectory of change in depressive symptomatology over the course of the perinatal period as related to interpersonal risk factors (marital quality and social support) in a sample of 69 low-income, mostly immigrant Latina mothers at high and low risk for depression. We found a significant linear change in depressive symptomatology from baseline (pregnancy) through the postpartum period. This decline was steeper for high-risk women who reported high levels of social support compared with those who reported low levels of social support. In addition, a greater decline in depressive symptom scores was found for women who reported better postnatal marital quality, irrespective of risk group status. The results suggest the importance of considering marital quality and social support in estimations of risk for depression. These findings also have implications for targeting social support and marital quality in preventive interventions for perinatal depression in Latinas.     

What did I eat yesterday? Determinants of accuracy in 24-hour food memories

Large-scale diet-related epidemiological work relies on the quality of self-reported food consumption. As this epidemiological work forms the basis of knowledge of the relationship of diet to disease, it is essential that the self-reports of personal diet are understood. It is generally accepted that foods consumed are under-reported, even over as short a period as 24 hours. However, little is known about the potential systematic biases that may affect the quality of self-reported food intake. The current study examines the accuracy of memories of the consumption of snack foods eaten in the previous 24 hours and investigates factors that may bias these memories. All participants had previously participated in a randomized intervention trial to lower dietary fat intake to 20 per cent of calories. Fifty-six women (intervention and control) tasted eight snack foods in a laboratory setting. They were telephoned a day later and asked to recall the type of snack foods (M&Ms, pretzels, etc.) and the quantity of each food they consumed. Subjects in general under-reported the number of selections and the quantity of each item consumed. Women who accurately recalled an item, reported more liking for that item compared to those who forgot the item. Women currently maintaining a low-fat diet were less accurate in their recall of low-fat items than women on a high-fat diet. Low-fat eaters, however, may be slightly better at recalling how much of certain foods they consumed. Results have implications for survey research and understanding the psychological influences on reports of food consumption used in large-scale diet studies.     

Depressive symptoms are associated with unrealistic negative predictions of future life events

This study examined the relationship between depressive symptoms and bias in the prediction of future life events. Responding to internet announcements, 153 participants varying widely in self-reported depression symptom severity estimated the probability of 40 events occurring over the succeeding 30 days. After the 30-day period, participants reported which events occurred. Optimistic/pessimistic biases were related to level of depressive symptoms. A non-significant optimistic bias characterized participants with low depressive symptoms whereas a significant pessimistic bias characterized participants with high depressive symptoms. Those reporting mild symptoms did not exhibit a systematic pessimistic or optimistic bias. General imprecision in predictions for undesirable events was associated with depressive symptoms. These findings suggest that depression is associated with pessimistic bias rather than accuracy in judgment.     

Military Observers' Reactions and Performance When Facing Danger

Some groups have to face threats and dangers professionally with maintained cognitive functioning, which implies a need to know both the extent to which maladaptive reactions occur and the factors that may affect it. This study examines self-reported reactions and performance when facing risks and dangers on peacekeeping observer missions. The sample consisted of 154 military observers. A self-made questionnaire, including the General Health Questionnaire and the Sense of Coherence (SOC) scale, was used. We found that feelings of invulnerability were common in relation to mission risks. In a specific danger incident, most participants subjectively performed well, although partial loss of cognitive functioning was reported in half of the cases and severely dysfunctional reactions in about one tenth. Cluster analysis showed that self-reported cognitive limitations in danger incidents were related to 2 factors: complicating situational factors, such as high levels of threat, complex decision demands, and minor control possibilities; and individual vulnerability factors, such as general worry and anger, low SOC, anxiety, and psychosomatic symptoms.     

Effects of combined treatment with vitamins C and E on passive avoidance learning and memory in diabetic rats

Learning and memory deficits occur in diabetes mellitus. Although the pathogenesis of cognitive impairment in diabetes has not been fully elucidated, factors such as metabolic impairments, vascular complications and oxidative stress are thought to play possible roles. Here we investigated the effect of chronic treatment with vitamin C (50 mg/kg, p.o), vitamin E (100 mg/kg, p.o) and both together on passive avoidance learning (PAL) and memory in male Wistar control and diabetic rats. Treatments were begun at the onset of hyperglycemia. Passive avoidance learning was assessed 30 days later. Retention was tested 24 h after training. At the end, animals were weighed and blood samples were drawn for plasma glucose measurement. Diabetes caused impairment in acquisition and retrieval processes of PAL and memory. The combination of vitamin C and E improved learning and memory in controls and reversed learning and memory deficits in diabetic rats. Combined treatment also affected the body weight and plasma glucose level of diabetic treated animals compared to untreated diabetic animals. Hypoglycemic effects and antioxidant properties of the vitamins may be involved in the nootropic effect of such treatment. These results show that combined treatment with vitamins C and E improved PAL and memory of control rats. In addition, combined vitamins administration to rats for 30 days from onset of diabetes alleviated the negative influence of diabetes on learning and memory. Therefore, combined vitamins treatment may provide a new potential alternative for prevention of impaired cognitive functions associated with diabetes and may warrant further clinical study.
