Stability and changes in health behaviours in young adults over a one year period

Abstract

Data concerning 19 health-related behaviours and associated beliefs were collected by questionnaire from 282 students in the Netherlands on two occasions over one year. While all behaviours showed moderate stability, there were variations in the degree of change. The highest stability was reported for sleep time, tooth brushing frequency, seat belt usage and health care service utilization. The least stable behaviours included regular exercise and various dietary measures. Predictors of changes in smoking, dietary fat intake, alcohol consumption and regular exercise were analysed in detail. Beliefs assessed at year 1 in the importance of these activities for health predicted changes in behaviour over the study year independently of prior behaviour levels. Awareness of the risks associated with behaviours, and explicit wishes to modify behaviour patterns (eg stop smoking, exercise more), did not predict change from year 1 to year 2. The results indicated that health behaviours vary in their stability, and that health beliefs may predict future health behaviour changes.     

Social relationships,stressful life events,and self-reported physical health: Genetic and environmental influences

Abstract

This study investigates how the associations between self-reported health, stressful life events, and social relationships are mediated by genetic and environmental influences and how much of the variance in health is in common with variation in these psychosocial factors. The analyses are based on questionnaire data from 576 pairs of twins reared apart and twins reared together. The data revealed that for men environmental influences were solely important for variation in the psychosocial measures and were the primary mediators of the relationship with health. For women, on the other hand, a substantial portion of the variance in the psychosocial factors was due to genetic influences and these influences also contributed to the bulk of the correlations with health. The gender differences for the relationships and their mediation indicate that what should be regarded as a psychosocial factor of importance for health might differ between genders.     

‘I feel better when…’: An analysis of the memory-experience gap for peoples’ estimates of the relationship between health behaviours and experiences

Objective: People often overestimate how strongly behaviours and experiences are related. This memory-experience gap might have important implications for health care settings, which often require people to estimate associations, such as “my mood is better when I exercise”. This study examines how subjective correlation estimates between health behaviours and experiences relate to calculated correlations from online reports and whether subjective estimates are associated with engagement in actual health behaviour.

Design: Seven-month online study on physical activity, sleep, affect and stress, with 61 online assessments.

Main Outcome Measures: University students (N = 168) retrospectively estimated correlations between physical activity, sleep, positive affect and stress over the seven-month study period.

Results: Correlations between experiences and behaviours (online data) were small (r = ?.12–.14), estimated correlations moderate (r = ?.35–.24). Correspondence between calculated and estimated correlations was low. Importantly, estimated correlations of physical activity with stress, positive affect and sleep were associated with actual engagement in physical activity.

Conclusion: Estimation accuracy of relations between health behaviours and experiences is low. However, association estimates could be an important predictor of actual health behaviours. This study identifies and quantifies estimation inaccuracies in health behaviours and points towards potential systematic biases in health settings, which might seriously impair intervention efficacy.     

Preventive behaviour and health status among the elderly

Abstract

The research describes the range of preventive health behaviours undertaken by the elderly, investigates the dimensionality of preventive health behaviour, and explores the relationship between preventive health behaviour, self-assessed and medically assessed health status. Previous research has relied mainly on self-reports of health status. Data from medical examinations and interviews with 115 elderly individuals (aged 65–75) indicated that most elderly persons performed some intentional preventive health practices, as well as a broad range of normative preventive health practices. Particular clusters of preventive health behaviour emerged when the data were subjected to cluster analysis. A short index consisting of five personal preventive health behaviours found in other studies to have a protective effect on long-term health was found to have a low to moderate correlation with the medical and self-assessments of health status employed in the study. These findings indicate particular types of preventive health behaviour of importance for health promotion programmes with the elderly.     

Health enhancing physical activity as perceived in interviews based on the theory of planned behaviour

Abstract

The perception of behaviours from two categories of health enhancing physical activity (HEPA): outdoor aerobic exercise (OAE) and everyday commuting activity (ECA) was examined in a sample of middle-aged persons (N= 50). A focused semi-standardised interview was constructed on the bases of the components of the Theory of Planned Behaviour (TPB). The participants perceived OAE behaviours predominantly from the viewpoint of exercise and those of the ECA from that of the fluency of daily routines. They considered the OAE as sensible and associated it with positive health or fitness outcomes, but only those practising it also attributed positive psychological effects to OAE behaviours. A slightly better congruence with the TPB was found for the OAE behaviours than for those of the ECA. The difference is discussed in the light of the higher degree of decisional control with the OAE behaviours and the greater psychological heterogeneity of the ECA.     

Menopausal stage and age and perceptions of body image

Abstract

The aim of This study was to investigate the association between menopausal stage and age and women's perception of their body image. Females from a community sample (n = 304. age range from 35 to 65 years) volunteered to complete a structured questionnaire which contained the Multidimensional Body Self Relations Questionnaire (MBSRQ) and the Stunkard Body Shape Figure Scale. One hundred and twenty women were premenopausal, 76 women were perimenopausal and 108 were postmenopausal. The effects of age and menopausal stage could not be separated in ratings of appearance evaluation, fitness evaluation, current, ideal and societal ratings of the Stunkard Body Shape Figure Scale. Premenopausal women (who were likely to be younger) had more positive ratings of appearance evaluation and fitness evaluation than menopausal women (who were likely to be older). Women who were premenopausal nominated smaller figures from the Stunkard Body Shape Figure Scale for ratings of the current, ideal and societal body shape than women who were perimenopausal and postmenopausal. The implications of these findings as they relate to women as they progress through the menopausal transition and as they become older is discussed.     

Psychological and social characteristics of attenders for breast screening

Abstract

Demographic characteristics, health behaviour and knowledge of breast cancer were assessed in 183 women from a regional breast screening unit and compared with those of 182 women from a breast clinic and 41 control subjects. A questionnaire yielded information on (i) demographic characteristics and cancer-related behaviours including breast self-examination (BSE), use of screening and promptness of presentation of breast symptoms in the clinic group, (ii) the extent and effects of knowledge about breast cancer and (iii) the role of Health Belief Model dimensions. Results showed the screening unit attenders to be significantly older and to be significantly more likely to be from higher social classes. Differences between the groups in health beliefs and knowledge did not remain once the effects of age and social class were partialled out. While attitudes towards BSE and its practice related to health beliefs. only a minority of the women indicated that they practised BSE with any regularity. The results suggest that screening is failing to attract a truly representative sample of the community and raise the possibility that this failure is a consequence of sociological as much as psychological factors.     

Social-class indicators differentially predict engagement in prevention vs. detection behaviours

Objective: Few systematic studies have examined the contexts in which social-class variables will predict engagement in health-relevant behaviours. The current research examined whether the impact of social-class on health behaviours depends upon how social-class is assessed and the category of health behaviour under consideration.

Method: Our sample was drawn from the Health Information National Trends Survey in 2012 (N = 3959). Participants reported their income and education as well as their engagement in a variety of prevention and detection behaviours.

Results: Consistent with our hypothesised framework, we found that income predicted engagement in a variety of detection behaviours above and beyond education, whereas education predicted engagement in a variety of prevention behaviours above and beyond income.

Conclusions: Our findings suggest that income and education operate on health behaviours via different pathways and have implications for public health policy and intervention.     

Physical fitness and prior physical activity are both associated with less cortisol secretion during psychosocial stress

Background: Evidence linking fitness and decreased psychosocial stress comes from studies of athletes and typically relies upon self-report measures. Furthermore, there is little evidence regarding the impact of physical activity (PA) prior to a stressor. The aims of this study were to determine whether fitness and prior PA influence cortisol concentrations during psychosocial stress.

Methods: Seventy-five non-athletic participants took part in a submaximal walk prior to the Trier Social Stress Test for Groups (TSST-G). During the walk, fitness was assessed using heart rate (HR). A further 89 participants took part in the TSST-G without the walk. Stress responsiveness was assessed using salivary cortisol collected at 10-min intervals on seven occasions.

Results: Hierarchical multiple regression revealed that average walking HR accounted for 9% of the variance in cortisol secretion (P?=?.016), where a higher HR was associated with higher cortisol secretion. Between-subjects ANCOVA revealed that the walking group had a significantly lower cortisol secretion than the non-walking group (P?=?.009).

Conclusions: These findings indicate that fitter individuals have reduced cortisol secretion during psychosocial stress. They also indicate that prior PA can reduce cortisol concentrations during psychosocial stress and are suggestive of a role of PA in reducing the impact of stress on health.     

Family characteristics and health behaviours of adolescents and families

Abstract

The relationship between general family characteristics, represented by family cohesion and adaptability, and health behaviours (smoking, alcohol use, food choice, sleeping, Body Mass Index, and physical activity) is studied in a first study of 429 adolescents and young adults, and in a second study of 522 family triads (adolescent-mother-father). Using cluster analysis, adolescent groups with four different profiles of health behaviour were identified. Very similar results were found in the two studies. The health behaviour patterns in the different subgroups show that forms of (un)desirable health behaviours are interrelated in some clusters. Adolescents in the most healthy clusters, consistently reported highest levels of family cohesion. The relationship between family adaptability and health behaviours showed only limited significance. In families characterised by a high level of emotional bonding between family members together with stability and regularity in roles rules and power structure, adolescents' behaviour is the most healthy. The findings suggest that parental involvement is desirable in health promotion intervention. Further, it seems possible that health behaviours originate from a relatively small set of family Characteristics and that modifying family interactions might be powerful, albeit very difficult to do so, in changing a variety of health behaviours in adolescents.     

Predictors of exercise program participation in older women

Abstract

This study examined predictors of exercise program participation in females aged 60 to 89 years of age. Fifty-five exercise program participants and 50 non-exercising subjects were assessed on potential group predictor variables. Univariate analyses indicated that the Exercise compared to the Non-Exercise group had a stronger belief that they did not receive enough exercise in their everyday lives and in the health value of exercise, greater self-efficacy and enjoyment of exercise, and less physical discomfort associated with exercise. The Exercise group perceived exercise programs to be more available and greater family support to participate. Medical advice to exercise and exercise history did not differ significantly between groups. A logistic regression analysis indicated that of the variables assessed, belief that one is not receiving enough exercise in daily life and exercise availability were the most powerful predictors of exercise group membership. The implications of these findings for the promotion of exercise in older women are discussed.     

Self-efficacy,planning, and preparatory behaviours as joint predictors of physical activity: A conditional process analysis

Objective: Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual’s level of self-efficacy.

Methods: A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N = 166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model.

Results: Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours.

Conclusion: Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity.     

A daily diary study of internalised weight bias and its psychological,eating and exercise correlates

Objective: The current investigation extends ecological momentary assessment (EMA) and daily diary weight stigma research in internalised weight bias (IWB). This investigation used daily diaries to examine the relationship between IWB, mood, coping, body appreciation, exercise behaviours and eating behaviours. Design: The study sample consisted of individuals who were overweight or obese (85% female) with M_BMI?=?36.0, SD_BMI?=?6.2. Participants completed a daily diary each evening and wore a Fitbit for 30 days. Main Outcome Measures: Participants reported on IWB, mood, coping, body appreciation, exercise behaviours and eating behaviours.

Results: Both within- and between-subjects IWB were significantly related to positive affect, negative affect, several coping responses, body appreciation, eating behaviours and the urge to avoid exercise. Exploratory analyses indicated that positive and negative affect mediated many of the associations between IWB and coping responses, body appreciation, and eating and exercise behaviours.

Conclusion: This investigation provides evidence that IWB experiences have daily impacts on psychological well-being, body appreciation, coping, eating and exercise behaviours. Also, this study raises awareness about IWB and its potential impact on psychological well-being and health behaviours.     

Understanding behavioural clusters: Identifying differences between clusters of health behaviours on key constructs

Objective: To uncover the rationale underlying the perceived distinction between clusters of health behaviours by identifying cognitive constructs that differentiate among them, and creating a ‘cognitive profile’ for each behavioural cluster. Thus, different determinants and characteristics of health behaviours (e.g. ‘perceived behavioural control’, ‘impact on health’, ‘effort’, ‘non-health rewards’, ‘habit’) were used to compare health behaviour meta-clusters (physical and psychosocial) and clusters (e.g. nutrition behaviours, substance abuse, medical practices).

Methods: A sample of lay people (N = 1956) judged items representing behavioural clusters delineated in the Health Behaviour Taxonomy on 14 constructs.

Results: Significant differences emerged between the physical and psychosocial meta-clusters, as well as among their sub-clusters. For example, physical behaviours were higher on ‘perceived behavioural control’ and ‘impact on health’ compared to psychosocial behaviours, and nutrition was perceived highest on ‘effort’ and ‘non-health rewards’ compared to the other clusters of the physical meta-cluster.

Conclusion: The findings increase our understanding of the logic underlying lay people’s cognitive schema of health behaviour clusters. ‘Cognitive profiles’ that explain differences between the clusters were identified, which can be used to design health messages and interventions targeting multiple health behaviours.     

Psychosocial Factors Relating to Adaptive Capacity in a New Zealand District Health Board

ABSTRACT

Communities assume that health care systems are adequately preparing for disasters, yet health sector capacities are restricted. The current research examined factors associated with adaptive capacity of staff in the New Zealand health sector. Two studies were carried out in the context of large-scale emergency management exercises, with the assumption that such exercises provide information about psychosocial responses to real emergency situations. The focus of the research was on adaptive capacity to address routine work-related stressors, as high levels of routine demands in the health sector have implications for staff health and organizational functioning, both of which are important for managing the stressful demands arising from emergency situations. The implications of these findings are discussed.     

Unpacking the debate: A qualitative investigation of first-time experiences with interval exercise

ObjectiveThere has been compelling debate about whether interval exercise should be promoted in public health strategies as a means of eliciting the health and fitness adaptations associated with physical activity behavior, particularly among individuals who are inactive. Despite a rapidly growing body of quantitative research, there is a notable absence of qualitative research on the topic. This study used a series of interviews conducted over time to develop a richer understanding of inactive adults’ experiences and perceptions of moderate-intensity continuous training (MICT), high-intensity interval training (HIIT), and sprint interval training (SIT) over time and factors that may influence their participation in these types of exercise.MethodsThirty inactive young adults (18 women, 12 men) completed three lab-based trials of cycling exercise in a random order on separate days: MICT, HIIT, and SIT, and subsequently logged their free-living exercise over four weeks. Interviews were conducted at five timepoints and subjected to a reflexive thematic analysis.ResultsThree overarching themes were constructed: (1) interval exercise sounds appealing, but is it for me? (2) exercise trade-offs – the value of interval vs. traditional exercise, and (3) real-world exercise adaptations to make it on your own.ConclusionsThe findings emphasize that people respond differently to different forms of exercise and the factors that influence participation in interval or continuous exercise are far more complex than can be captured by quantitative methodologies alone. Results suggest there is indeed a place for interval exercise in exercise plans and programs for the general population and interval exercise can be used concurrently with continuous exercise.     

Main and interactive effects of social support in predicting mental health symptoms in men and women following military stressor exposure

Abstract

Evidence across a multitude of contexts indicates that social support is associated with reduced risk for mental health symptoms. More information is needed on the effectiveness of different sources of support, as well as sex differences in support. Associations between social support from two sources – the military unit and friends and family – and mental health symptoms were examined in a study of 1571 Marine recruits assessed at the beginning and end of a highly stressful 13-week training program. Military social support buffered the stressor exposure–posttraumatic stress symptomatology (PTSS) relationship, whereas the relationship between stressor exposure and PTSS was highest when civilian social support was high. Further inspection of the interactions revealed that military support was most important at high levels of stressor exposure. Sex differences in the relationship between social support and symptoms were found, such that support from military peers was associated with lower levels of PTSS for men, whereas civilian support was associated with lower PTSS for women. While civilian social support was associated with lower levels of depression symptom severity in both women and men, the relationship was stronger for women. Reviewed implications focus on the importance of considering the recipient, source, and context of social support.     

Exercise training and health-related quality of life in generalized anxiety disorder

ObjectiveTo quantify the effects of six-weeks of resistance (RET) and aerobic exercise training (AET) on quality of life (QoL) among sedentary women with Generalized Anxiety Disorder (GAD).DesignData from our published randomized controlled trial of the effects of six-weeks of either RET or AET among GAD patients were analyzed.MethodThirty women with GAD were randomized to either six weeks of twice-weekly lower-body weightlifting or cycling, or wait-list control (WL). SF-36 subscales assessed dimensions of QoL. Hedges’ d effect sizes (95%CIs) quantified the magnitude of change in response to exercise training compared to WL.ResultsRET significantly improved role-physical (d = 1.04; 95%CI: [0.11–1.97]), role-emotional (d = 0.96; [0.04–1.89]), and mental health (d = 1.05; [0.11–1.98]). AET resulted in significant improvements in physical function (d = 1.31; [0.34–2.27]) and vitality (d = 0.93; [0.01–1.85]).ConclusionsExercise training improves dimensions of QoL among GAD patients. The largest effects were observed for role impairments, physical function, vitality, and mental health.     

‘Sticking to a healthy diet is easier for me when I exercise regularly’: Cognitive transfer between physical exercise and healthy nutrition

Objective: Long-term rehabilitation success depends on regular exercise and healthy nutrition. The present study introduces a new framework to explain this association on a psychosocial level. The exercise–nutrition relationship was investigated by exploring the sequential mediation of habit strength and transfer cognitions.

Design: Analyses were performed at two measurement points in time (at 12 and 18?months after rehabilitation), involving 470 medical rehabilitation patients who participated in an exercise intervention.

Main outcome measures: Patients filled in paper-pencil questionnaires assessing exercise (t1) and habit strength, transfer cognitions and healthy nutrition at follow-up (t2).

Results: Habit strength and transfer cognitions mediated the relationship between exercise and nutrition.

Conclusion: Findings suggest that habit strength and transfer cognitions are important factors underlying the relationship between exercise and nutrition.     

Understanding physical activity behavior and cognitions in pregnant women: An application of self-determination theory

ObjectivesAlthough regular exercise during pregnancy is linked with improved health outcomes for both mother and foetus, many pregnant women are inactive. The purpose of this study was to use organismic integration theory (OIT) as the guiding theory for examining the relationship between autonomous and controlled motives for (a) exercise behavior reported over a typical week and barriers to exercise and (b) exercise and stage of pregnancy (i.e., trimester).DesignCross-sectional.MethodsParticipants (N = 75) were pregnant women who completed a multi-component, Internet-based survey.ResultsMultiple regression analyses showed that identified regulation predicted greater exercise behavior and fewer exercise barriers, irrespective of trimester. Further analyses indicated that women in the first trimester reported significantly higher identified regulation compared to women in either second or third trimesters.ConclusionsOverall, these findings reinforce the importance of distinguishing controlled from autonomous exercise motives and demonstrate the tenability of OIT for enhancing our understanding of exercise behavior and barriers during pregnancy.
