Childhood physical and sexual abuse,and adult health risk behaviours among university students from 24 countries in Africa,the Americas and Asia

The goal of this study was to retrospectively estimate the prevalence of childhood physical abuse (CPA) and childhood sexual abuse (CSA) in relation to experience of adult violence, poor mental health, addictive behaviour and sexual risk behaviour among university students from 24 countries in Africa, the Americas and Asia. In a cross-sectional survey, data were collected from 18 404 undergraduate university students (mean age 20.7, SD = 2.9, age range of 16–30 years) from 24 countries. Overall, 5.0%, 2.6% and 1.2% of the students reported childhood physical abuse, childhood sexual abuse and childhood physical and sexual abuse, respectively. In the logistic regression models, adjusting for age, sex, study year, family wealth, and country, having experienced CPA and CSA was associated with increased odds of having any adult violence (physical and sexual partner violence victimisation. Having been in a physical fight, and weapon carrying), any poor mental health (post-traumatic stress disorder, depression symptoms and sleeping problems), addictive behaviour (tobacco use, binge drinking, frequent gambling and obesity) and sexual risk-taking was higher with a self-reported history of CPA and CSA.     

Exploring the psychometric properties of the CES-D-10 and its practicality in detecting depressive symptomatology in 27 low- and middle-income countries

The Center for Epidemiological Studies Depression-10 (CES-D-10) scale is known for its good psychometric properties in measuring depressive symptoms, however, some researchers question its applicability across various settings. This study explored the factor structure of the CES-D-10 in low- and middle-income countries (LMICs). This cross-sectional survey consisted of 16,723 university students across 27 LMICs that completed self-report instruments assessing socio-demographic information and depressive symptoms using the CES-D-10. Data analysis included: exploratory factor analysis, item response theory and differential item functioning. Results indicate that a two-factor model (depressive affect and positive affect) had the best fit for this population and accounted for 52% of the total observed variance with an internal consistency, α = .77 for the depressive affect items and α = .57 for the positive affect items. The graded response model (GRM), however, indicated that the depressive affect factor had a good fit, unlike the positive affect factor. The depressive affect factor was found to consistently model depression for females better than males. Relative to their Asian counterparts, African, Caribbean and South American participants of similar depressive affect responded differently on all items of the depressive affect factor. The depressive affect factor seems most ideal for LMICs and shows gender and cross-cultural variability.     

Happiness and health behaviours among university students from 24 low,middle and high income countries

The aim of this study was to examine health behaviours and happiness and associated factors in low, middle and high income countries. In a cross-sectional survey, 17 508 undergraduate university students (mean age 20.9, SD = 2. 8) from 25 universities in 24 countries across Asia, Africa and the Americas self-completed anonymous questionnaires. Results indicate that the overall happiness mean score among university students across 24 countries was 13.7 (range 4–20). Generally, the study found that university students from countries of the Caribbean, South America and sub-Saharan Africa had greater happiness scores than students from countries in North Africa and Asia. In multivariate linear regression analysis, better subjective socio-economic status, coming from an higher income country, higher social support, higher intrinsic religiosity, higher personal mastery, positive health behaviours (regular breakfast, adequate physical activity, habitual seatbelt use, regular dental check-ups, not having had an injury, not drinking and driving) and negative health behaviours (not having three or more servings of vegetables and eating red meat daily) were correlated with happiness. Improvement to the happiness of university students should consider regional differences in socio-economic environment.     

Lifestyle and mental health among school-going adolescents in Namibia

This study examined the association between lifestyle behaviours and psychological distress indicators among school-going adolescents. The analysis included 4 531 school children, 11–18 years of age, who completed the Namibia Global School-based Student Health Survey (GSHS) in 2013. Multivariable logistic regression analysis found that engaging in a greater number of harmful consumptive, sedentary and sexual risk behaviours carried an elevated risk for anxiety, suicide attempt and loneliness. Adolescents with co-occurring health risk behaviours have poorer mental health outcomes with socio-economic vulnerability.     

Body weight and weight perception among African and Caribbean university students: Correlation with depression symptoms

The aim of the study was to investigate the association between body weight, weight perception, and depressive symptoms in African and Caribbean university students. In a cross-sectional survey the total sample included 4 964 undergraduate university students (mean age 21.8, SD = 3.4, age range = 18-30 years) from five African and three Caribbean countries. Data on the students’ actual and perceived body weight, as well as depression symptoms, were collected. In logistic regression, perceived rather than measured overweight predicted depressive symptoms in male students with normal weight. For female students, perceived overweight predicted depression symptoms regardless of actual body weight. Male students who overestimated their body weight were at greater risk of depressive symptoms. Body weight self-perceptions appear to influence experience of mood disorder among African and Caribbean country students.     

Alcohol use among adults in Kenya: Results from the National Non-Communicable Diseases Risk Factor survey, 2015

The aim of this study was to assess the prevalence and correlates of alcohol use among Kenyan adults. We analysed data from the Kenya cross-sectional national Non-Communicable Diseases Risk Factor survey, 2015. The survey sampled 4 469 adults (median age 38.0 years, interquartile range = 23, age range of 18–69 years). Results indicate that 6.7% were hazardous or harmful alcohol users and 12.8% past month binge-drinkers. In adjusted logistic regression analysis, being male, middle aged, belonging to the Luhya or Kalenjin ethic group, tobacco use, and having hypertension increased the odds for hazardous or harmful alcohol use. Socio-demographic and health factors appear to influence risk for hazardous or harmful alcohol use among adults in Kenya.     

Post-traumatic stress disorder and health risk behaviour among persons 15 years and older in South Africa

The aim of this study was to investigate the association between post-traumatic stress disorder (PTSD) and health risk behaviours among persons 15 years and older in South Africa. We analysed data from the South African National Health and Nutrition Examination Survey (SANHANES-1, 2012) (N = 15 201; mean age = 36.9 years, SD = 16.5; 2.1% with PSTD, 4.0% with partial PTSD). The survey included questions from validated measures of the following health risk behaviours: problem drinking, current tobacco use, physical activity, sedentary behaviour, vegetable consumption, and fast food and frequent soft drinks consumption. In adjusted logistic regression analysis, only self-reporting with PTSD was associated with problem drinking. The data did not yield significant association between PTSD status and any of the other health risk behaviours (tobacco use, low physical activity, and fast food consumption).     

Mental health correlates of HIV risk behaviour and STIs/HIV infection among university students from 22 low,middle and high income countries

The aim of this study was to determine mental health correlates of HIV risk behaviour and self-reported STIs/HIV infection among university students in 22 low, middle and high income countries. Data on mental health and HIV risk were collected from 16 567 undergraduate university students (mean age 20.9, SD = 2.9) from 23 universities in 22 countries across Asia, Africa and the Americas. Results indicate that overall 16.8% of the students had two or more sexual partners in the past 12 months, and among the sexually active, 73.7% had inconsistently used a condom in the past three months with their primary sexual partner, 3.2% had ever been diagnosed with a sexually transmitted infection (STI) and 0.6% had been diagnosed with HIV. In multivariate logistic regression poorer mental health and child abuse (physical and sexual) were associated with HIV risk behaviour, and child abuse (physical and sexual) was associated with STI and HIV positive diagnoses.
