BACKGROUND: Suicide is a major public health issue. AIM: This study aimed to assess the prevalence and correlates of lifetime suicide attempts and past 12-month suicidal behaviour (ideation, plans and/or attempts) among adults (18-69 years). SETTING: Zambia. METHOD: National cross-sectional data from 4302 adults (median age: 31 years) who took part in the '2017 Zambia STEPS survey' were analysed. RESULTS: The results indicate that 2.3% of participants had ever attempted suicide and 8.5% engaged in past 12-month suicidal behaviour (ideation 7.8%, plan 3.6% and/or attempt 1.1%). In adjusted logistic regression analysis, having a family member who died from suicide, having had a heart attack, angina or stroke and daily tobacco smoking were associated with ever suicide attempt. In adjusted logistic regression, female sex, non-paid work status (including student, homeworker and retired), alcohol use-related family problem, passive smoking, heart attack, angina or stroke and alcohol dependence were positively associated with past 12-month suicidal behaviour, and belonging to other ethnic groups was negatively associated with past 12-month suicidal behaviour. In addition, in an unadjusted analysis, 18-24-year-old participants, those who were never married, separated, divorced or widowed, having urban residence, family members died from suicide, having lower systolic blood pressure and daily smokeless tobacco use, were associated with past 12-month suicidal behaviour. CONCLUSION: Almost 1 in 10 participants was engaged in suicidal behaviour in the past 12 months, and several associated indicators were found that can assist in planning interventions.

BACKGROUND: Harmful alcohol and illicit drug use significantly contribute the burden of disease. AIM: This study aimed to assess the prevalence and correlates of hazardous, harmful or dependent alcohol (HHDA) use and drug use amongst persons 15 years and older in South Africa. SETTING: Population-based survey. METHOD: In a national cross-sectional 2017 survey, 39 210 persons 15 years and older (Median = 34 years) responded to a questionnaire on substance and health variables. The prevalence of HHDA use was 10.3% and past 3-month drug use 8.6%. RESULTS: In adjusted logistic regression analysis, men of middle age (25-34 year olds) with higher education, urban residence, drug use and psychological distress were positively associated and Indian or Asian and white population groups were negatively associated with HHDA. Women of middle age (25-34 year old) and mixed race, residing on rural farms and urban areas, with drug use and psychological distress were positively associated and older age (55 years and older) and Indians or Asians were negatively associated with HHDA. In adjusted logistic regression analysis, men, having Grade 8-11 education, mixed race, being unemployed, and the HHDA used were positively associated and middle and older age (25 years and older) and being a student or learner were negatively associated with past 3-month any drug use. Women, who were mixed race, Indians or Asians, with the HHDA use were positively associated and older age (45 years and older) were negatively associated with the past 3-month drug use. CONCLUSION: About one in 10 participants with several sociodemographic and health indicators was identified to be associated with HHDA and any drug use.

BACKGROUND: Tobacco use may deteriorate mental health and increase health risk behaviours. AIM: The aim of this investigation was to identify associations between tobacco use and mental illness symptoms and health risk behaviours in individuals 15 years or older in South Africa. SETTING: Community-based national population sample in South Africa. METHODS: Cross-sectional data were analysed from the 'South African National Health and Nutrition Examination Survey (SANHANES-1) 2012', using a sample of 15 310 individuals 15 years or older (median age 33 years). Measures included information on tobacco use, sociodemographic factors, mental symptoms and health risk behaviour. RESULTS: Compared to non-tobacco users, daily tobacco users were associated with psychological distress and post-traumatic stress disorder (PTSD) in adjusted logistic regression analysis, and with sleeping problems in unadjusted analysis. Past tobacco use, less than daily, and daily tobacco use were highly associated with a drinking problem. In terms of dietary variables, less than daily and daily tobacco use increased the odds of inadequate fruit intake and salty food intake, and daily tobacco use decreased the odds of fast food consumption. Past tobacco use, less than daily, and daily tobacco use were inversely associated with physical inactivity, and daily tobacco use was associated with not always washing hands before eating. CONCLUSIONS: The study showed that compared to non-tobacco users, daily tobacco users had significantly poorer mental health (psychological distress and PTSD) and increased odds for several health risk behaviours (drinking problem, inadequate fruit intake, salty food consumption and not always washing hands before eating) as compared to non-tobacco users.

OBJECTIVE: Alcohol use in pregnancy is linked with various negative health effects on the infant. The aim of this study was to examine the prevalence of maternal alcohol use during pregnancy and socio-demographic and health correlates. METHODS: Data of ever-pregnant women from the cross-sectional 'South African National Health and Nutrition Examination Survey (SANHANES-1) 2011-2012' were analysed. The sample included 5089 adolescents and adult women aged 15-55 years. They responded to questions on alcohol use, socio-demographic and health indicators. RESULTS: The results indicated that 3.7% (95.0% confidence interval [CI] = 3.1, 4.5) of South African women had engaged in alcohol use during their pregnancy. In adjusted analysis, being mixed race, not employed, poor self-rated health status, ever been diagnosed with tuberculosis and having partial post-traumatic stress disorder were found to be associated with alcohol use during pregnancy. CONCLUSIONS: The study findings suggest links between socio-demographic and health variables and prenatal alcohol use, which may have public health policy implications.

BACKGROUND: There is lack of information on the correlates of sedentary behaviour among persons with alcohol use disorders. The study aimed to examine socio-demographic and health correlates among adolescents and adults with hazardous, harmful or probable dependent alcohol use (= problem drinking METHOD: Data from the cross-sectional South African National Health and Nutrition Examination Survey (SANHANES-1) 2011-12 were analysed. From a total sample of 15 085 persons aged 15 years and older, 2849 adolescents and adults (mean age = 37.1 years, standard deviation [s.d.] = 15.1) were identified as problem drinkers, based on the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C). Multivariable logistic and linear regression were used to determine the associations between socio-demographic characteristics, health variables and high sedentary behaviour (≥8 h/day) and total minutes of sedentary behaviour a day RESULTS: The prevalence of high sedentary behaviour (≥ 8 h/day) was 11.9% overall (11.9% among men and 12.1% among women), and the mean (s.d.) duration of sedentary behaviour was 263 (169) min/day. In bivariate analysis, older age, population group, functional disability, cognitive impairment, having hypertension, having had a stroke and posttraumatic symptoms were correlated with high sedentary behaviour. In adjusted logistic regression analysis, older age and being Indian or Asian were positively, and having been diagnosed with angina was negatively, associated with high sedentary behaviour. In linear regression analysis, older age, not employed and having had a stroke were positively, and being of mixed race and having angina were negatively, associated with total minutes (up to 960 min/day) of sedentary behaviour in a day CONCLUSION: The study provides socio-demographic and health correlates of sedentary behaviour among problem drinkers. This information can guide possible future interventions in reducing sedentary behaviour among problem drinkers

BACKGROUND: Some research seems to suggest that physical activity (PA) was beneficial for post-traumatic stress disorder (PTSD). AIM: This study examined the association between levels of PA and PTSD among individuals 15 years and above in South Africa. SETTING: Community-based survey sample representative of the national population in South Africa. METHODS: In all, 15 201 individuals (mean age 36.9 years) responded to the cross-sectional South African National Health and Nutrition Examination Survey (SANHANES-1) in 2012. RESULTS: One in five (20.1%) of participants reported exposure to at least one traumatic event in a lifetime, and 2.1% were classified as having a PTSD, 7.9% fulfilled PTSD re-experiencing criteria, 3.0% PTSD avoidance criteria and 4.3% PTSD hyperarousal criteria. Almost half (48.1%) of respondents had low PA, 17.4% moderate PA and 34.5% high PA. In logistic regression analysis, adjusted for age, sex, population group, employment status, residence status, number of trauma types, problem drinking, current tobacco use, sleep problems and depressive symptoms, high PA was associated with PTSD (odds ratio [OR] = 1.75, confidence interval [CI] = 1.11-2.75), PTSD re-experiencing symptom criteria (OR = 1.43, CI = 1.09-1.86) and PTSD avoidance symptom criteria (OR = 1.74, CI = 1.18-2.59), but high PA was not associated with PTSD hyperarousal symptom criteria. In generalised structural equation modelling, total trauma events had a positive direct and indirect effect on PTSD mediated by high PA, and high PA had a positive indirect effect on PTSD, mediated by psychological distress and problem drinking. CONCLUSION: After controlling for relevant covariates, high PA was associated with increased PTSD symptomatology.

BACKGROUND: There are limited studies assessing rural-urban disparities among older adults in Africa including South Africa AIM: This study explores rural-urban health disparities among older adults in a population-based survey in South Africa SETTING: Data for this study emanated from the 2008 study on 'Global Ageing and Adult Health (SAGE) wave 1' (N = 3280) aged 50 years or older in South Africa METHODS: Associations between exposure variables and outcome variables (health status variables and chronic conditions) were examined through bivariate analyses and multivariable logistic regression RESULTS: Rural dwellers were more likely to be older, black African and had lower education and wealth than urban dwellers. Rural and urban dwellers reported a similar prevalence of self-rated health status, quality of life, severe functional disability, arthritis, asthma, lung disease, hypertension, obesity, underweight, stroke and/or angina, low vision, depression, anxiety and nocturnal sleep problems. Adjusting for socio-demographic and health risk behaviour variables, urban dwellers had a higher prevalence of diabetes (OR: 2.36, 95% CI: 1.37, 4.04), edentulism (OR: 2.79, 95% CI: 1.27, 6.09) and cognitive functioning (OR: 1.91, 95% CI: 1.27, 2.85) than rural dwellers CONCLUSION: There are some rural-urban health disparities in South Africa, that is, urban dwellers had a higher prevalence of diabetes, edentulism and cognitive functioning than rural ones. Understanding these rural-urban health variations may help in developing better strategies to improve health across geolocality in South Africa

OBJECTIVE: To better understand conjoint alcohol and tobacco use among male hospital out-patients, the purposes of this study were: (1) to assess the prevalence of conjoint use and (2) to determine the factors associated with the conjoint alcohol use and tobacco use. METHODS: In a cross-sectional survey, consecutive male out-patients from four district hospitals in Nakhon Pathom province in Thailand were assessed with the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), Hospital Anxiety and Depression Scale (HADS), self-reported chronic conditions and health-seeking behaviour. The sample included 2208 study participants, with a mean age of 36.2 years (SD = 11.7) and an age range of 18-60 years. RESULTS: Overall, 34.5% of the male hospital out-patients were conjoint moderate or high-risk alcohol and tobacco users, and 31.1% were moderate or high-risk alcohol or tobacco users. In multivariate analysis, younger age, having primary or less education, being separated, divorced or widowed, not having diabetes and not being obese were associated with conjoint moderate or high-risk alcohol and tobacco use. CONCLUSION: High prevalence and several risk factors of conjoint alcohol and tobacco use were found among hospital male out-patients. The findings of this study call for dual-intervention approaches for both alcohol and tobacco.

OBJECTIVE: The aim of this study was to estimate the prevalence and relationship of anxiety and depressive features among patients diagnosed with a variety of chronic diseases in three Southeast Asian countries (Cambodia, Myanmar and Vietnam). METHODS: A cross-sectional survey was conducted in 2014 among 4803 adult patients with chronic diseases who were recruited cross-sectionally from health facilities. Anxiety and depression were assessed with the Hospital Anxiety and Depression Scale. RESULTS: Overall, 17.0% of patients screened positive for anxiety disorder and 39.1% for depressive disorder. Patients with cancer (47.8%) had the highest rate of anxiety features, and those with chronic obstructive pulmonary disease (COPD) (62.1%), kidney disease (55.5%), Parkinson's disease (53.7%) and cardiovascular disorders (CVDs) (52.6%) the highest prevalence of depressive features. Stomach and intestinal diseases, CVDs, migraine or frequent headaches and kidney disease were positively associated with anxiety and depression after adjusting for sociodemographics and illness duration. In addition, cancer and Parkinson's disease were positively associated with anxiety, and arthritis, diabetes, and COPD were positively associated with depression. In multivariate logistic regression, having two or more chronic conditions and poor quality of life was associated with anxiety and depression. CONCLUSION: Considering the high rate of anxiety and depression among these patients with chronic disease, more efforts should directed to on the psychosocial management of these patients.

OBJECTIVE: To quantify the prevalence of obesity and obesity-related factors in a crosssectional, observational study of Caribbean students using the results of three recent surveys of health behavior among undergraduates in Barbados, Grenada, and Jamaica. METHODS: A total of1 578 Caribbean undergraduate students from Barbados, Grenada, and Jamaica (ages 18-30 years) completed questionnaires and had physical measurements recorded. Multivariable logistic regression was used to estimate odds ratios (ORs) for the association of nutrition behaviors with prevalence of obesity (body mass index > 30 kg/m² ); elevated waist-to-height ratio (W/ht) (> 0.50); and high waist circumference (WC) (> 88 cm in females, > 102 cm in males). Models were adjusted for age, year in university, socioeconomic status, and sex. RESULTS: There was a higher prevalence of obesity (13% versus 10%), high WC (21% versus 7%), and high W/ht (35% versus 25%) in females relative to males. Compared to females, males had reduced odds of obesity (OR 0.46), high WC (OR 0.22), and high W/ht (OR 0.61) (P < 0.05 for all). Both females (46%) and males (24%) reported high levels of physical inactivity. Fruit and vegetable consumption was low (approximately two servings per day). Many students reported avoiding fatty foods (40%); this behavior was associated with high W/ht (OR 1.68), obesity (OR 1.90), and high WC (OR 1.82) (P < 0.05 for all). Irregular breakfast consumption, age, and year of study were also positively associated with obesity. Physical activity was not significantly associated with any obesity measure. CONCLUSIONS: There was a low prevalence of healthy behaviors and a high prevalence of obesity in this sample of Caribbean young adults.

OBJETIVO: Cuantificar la prevalencia de la obesidad y los factores relacionados con esta mediante un estudio transversal y de observación de estudiantes del Caribe, que utilizó los resultados de tres encuestas recientes sobre comportamientos con respecto a la salud en estudiantes de pregrado de Barbados, Granada y Jamaica. MÉTODOS: Un total de 1 578 estudiantes de pregrado caribeños de Barbados, Granada y Jamaica, de 18 a 30 años de edad, completaron cuestionarios y se sometieron a una serie de mediciones antropométricas, que fueron registradas. Se utilizó un modelo de regresión logística multivariable para calcular las razones de posibilidades (OR) de las asociaciones de los comportamientos nutricionales con la prevalencia de obesidad (índice de masa corporal > 30 kg/m²); índice cintura-talla (ICT) elevado (> 0,5); y circunferencia de la cintura (CC) elevada (> 88 cm en mujeres, > 102 cm en hombres). Los modelos se ajustaron para la edad, el número ordinal del curso universitario, la situación socioeconómica y el sexo. RESULTADOS: Se observó una mayor prevalencia de obesidad (13 frente a 10%), CC más elevada (21 frente a 7%) e ICT más elevado (35 frente a 25%) en las mujeres que en los hombres. En comparación con las mujeres, los hombres mostraron menores probabilidades de obesidad (OR 0,46), CC elevada (OR 0,22) e ICT elevado (OR 0,61) (P < 0,05 para todos ellos). Tanto las mujeres (46%) como los hombres (24%) notificaron altos niveles de inactividad física. El consumo de frutas y verduras era bajo (aproximadamente de dos raciones por día). Muchos estudiantes notificaron que evitaban los alimentos grasos (40%); este comportamiento se asoció con ICT elevado (OR 1,68), obesidad (OR 1,90) y CC elevada (OR 1,82) (P < 0,05 para todos ellos). El consumo irregular en el desayuno, la edad y el número ordinal del curso universitario también se asociaron positivamente con la obesidad. La actividad física no se asoció significativamente con ninguna medición de obesidad. CONCLUSIONES: En esta muestra de adultos jóvenes del Caribe se observó una baja prevalencia de comportamientos saludables y una alta prevalencia de obesidad.
