BACKGROUND: Despite a long history of discrimination and persisting racial disparities in smoking prevalence, little research exists on the relationship between discrimination and smoking in South Africa. METHODS: This analysis examined chronic (day-to-day) and acute (lifetime) experiences of racial and non-racial (eg, age, gender or physical appearance) discrimination and smoking status among respondents to the South Africa Stress and Health study. Logistic regression models were constructed using SAS-Callable SUDAAN. RESULTS: Both chronic racial discrimination (RR=1.45, 95% CI 1.14 to 1.85) and chronic non-racial discrimination (RR=1.69, 95% CI 1.37 to 2.08) predicted a higher risk of smoking, but neither type of acute discrimination did. Total (sum of racial and non-racial) chronic discrimination (RR=1.46, 95% CI 1.20 to 1.78) and total acute discrimination (RR=1.28, 95% CI 1.01 to 1.60) predicted a higher risk of current smoking. CONCLUSIONS: Racial and non-racial discrimination may be related to South African adults' smoking behaviour, but this relationship likely varies by the timing and frequency of these experiences. Future research should use longitudinal data to identify the temporal ordering of the relationships studied, include areas outside of South Africa to increase generalisability and consider the implications of these findings for smoking cessation approaches in South Africa.

OBJECTIVE: To describe relationships between tobacco-related environments and disparities in smoking by sexual orientation. METHODS: We examined three aspects of state-level tobacco environments, which were derived from the ImpacTeen State Level Tobacco Control Policy and Prevalence Database: (1) tobacco price and tax data and tobacco control funding; (2) tobacco control policies and (3) tobacco prevalence and norms data. This information was linked to individual-level data on sexual orientation, tobacco use and nicotine dependence in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N=34 653; 577 LGB respondents), a cross-sectional, nationally representative survey of adults in the USA. RESULTS: Lesbian, gay and bisexual (LGB) adults in states with more restrictive tobacco environments were less likely to have ever smoked (AOR=0.78, 95% CI 0.62 to 1.00) and to currently smoke (AOR=0.77, 95% CI 0.60 to 0.99) than LGB adults in more permissive tobacco environments. Further, sexual orientation disparities in past and current smoking, as well as in current nicotine dependence, were lower in states with the most restrictive tobacco environments. Results were robust to adjustment for confounders at the individual and state levels. CONCLUSIONS: Restrictive state-level tobacco environments are correlates of smoking behaviours among LGB adults in the USA; such environments could potentially reduce social inequalities in smoking based on sexual orientation.

Background Diaries are used in sexual behaviour research to reduce recall bias. Diary collection via mobile phone text messaging (SMS) has not been trialled previously in sexual behaviour research. This randomized controlled trial compared SMS, paper and online diaries on response rate, timeliness, completeness of data and acceptability. The correlation between behaviour reported in all three types of diaries and data collected in a retrospective questionnaire was also determined. Methods Participants were recruited by telephone and randomised into one of three groups. They completed weekly sexual behaviour diaries for 3 months by SMS, online or paper (by post). An online survey was conducted at the end of 3 months to compare retrospective reports to the diaries and assess opinions on the diary collection method. Results 72 participants were enrolled in the study, 24 in each group. Online diaries were more likely to be submitted late than SMS diaries (p<0.001). 3.9% of SMS diaries, 3.1% of paper diaries and 0.5% of online diaries were incomplete (p=0.001). Online data collection was the preferred mode for 51%. 65 participants completed the end point retrospective questionnaire. The correlation between the diary and questionnaire on sexual risk classification was substantial (κ=0.74) regardless of diary mode. Conclusions SMS is a convenient and timely method of collecting brief behavioural data, but online data collection was preferable to most participants and more likely to be complete. Data collected in retrospective sexual behaviour questionnaires were found to agree substantially with data collected through weekly self-reported diaries. [ABSTRACT FROM AUTHOR]

Introduction Tobacco manufacturers' aggressive promotion of new smokeless tobacco products such as snus warrants a timely and effective public health response. This study tested potential countermarketing messages to discourage current and former smokers from becoming dual users of smokeless tobacco and cigarettes. Methods In a pretest-post-test experiment, 1836 adult current and recently former smokers from a national sample were randomised to view one of six antismokeless tobacco ads followed by a snus ad, to view a control ad followed by a snus ad; or to view two control ads. Perceived effectiveness of ads and actual changes in attitudes and openness to snus were compared across groups using analyses of variance. Results Some ads that were perceived as most effective did not change attitudes or openness to trying snus, and conversely, some ads not perceived as effective changed attitudes and openness to snus. Ads portraying the negative health effects of smokeless tobacco were perceived as most effective, but ads with antitobacco industry themes significantly decreased favourable attitudes toward snus. Responses to ads were different for smokers who had ever used smokeless tobacco: for this group health effects and humorous/testimonial ads were effective. Conclusions Measures of perceived effectiveness of antitobacco ads need to be augmented with measures of actual effectiveness to assess countermarketing messages. Some of the developed ads, such as ads with anti-industry themes, were effective for the overall population of smokers whereas humorous/testimonial and health effects ads were particularly effective in changing attitudes of past users of smokeless tobacco.

Background Depression and obesity are significant health concerns currently facing adolescents worldwide. This paper investigates the associations between obesity and related risk behaviours and depressive symptomatology in an Australian adolescent population. Methods Data from the Australian Capital Territory It’s Your Move project, an Australian community-based intervention project were used. In 2012, 800 students (440 females, 360 males) aged 11–14 years (M=13.11 years, SD=0.62 years), from 6 secondary schools were weighed and measured and completed a questionnaire which included physical activity, sedentary behaviour and dietary intake. Weight status was defined by WHO criteria. A cut-off score ≥10 on the Short Mood and Feelings Questionnaire indicated symptomatic depression. Logistic regression was used to test associations. Results After controlling for potential confounders, results showed significantly higher odds of depressive symptomatology in males (OR=1.22, p<0.05) and females (OR=1.12, p<0.05) who exceeded guidelines for daily screen-time leisure sedentary activities. Higher odds of depressive symptoms were seen in females who consumed greater amounts of sweet drink (OR=1.18, p<0.05), compared to lower female consumers of sweet drinks, and males who were overweight/obese also had greater odds of depressive symptoms (OR=1.83, p<0.05) compared to male normal weight adolescents. Conclusions This study demonstrates the associations between obesogenic risks and depression in adolescents. Further research should explore the direction of these associations and identify common determinants of obesity and depression. Mental health outcomes need to be included in the rationale and evaluation for diet and activity interventions. [ABSTRACT FROM AUTHOR]

Background Evidence is conflicting regarding the relationship between low maternal alcohol consumption and birth outcomes. This paper aimed to investigate the association between alcohol intake before and during pregnancy with birth weight and gestational age and to examine the effect of timing of exposure. Methods A prospective cohort in Leeds, UK, of 1303 pregnant women aged 18-45 years. Questionnaires assessed alcohol consumption before pregnancy and for the three trimesters separately. Categories of alcohol consumption were divided into ≤2 units/week and ≥2 units/week with a nondrinking category as referent. This was related to size at birth and preterm delivery, adjusting for confounders including salivary cotinine as a biomarker of smoking status. Results Nearly two-thirds of women before pregnancy and over half in the first trimester reported alcohol intakes above the Department of Health (UK) guidelines of ≤2 units/week. Associations with birth outcomes were strongest for intakes ≥2 units/week before pregnancy and in trimesters 1 and 2 compared to non-drinkers. Even women adhering to the guidelines in the first trimester were at significantly higher risk of having babies with lower birth weight, lower birth centile and preterm birth compared to non-drinkers, after adjusting for confounders (p<0.05). Conclusions We found the first trimester to be the period most sensitive to the effect of alcohol on the developing fetus. Women adhering to guidelines in this period were still at increased risk of adverse birth outcomes. Our findings suggest that women should be advised to abstain from alcohol when planning to conceive and throughout pregnancy. [ABSTRACT FROM AUTHOR]

Background The Baby-Friendly Hospital Initiative (BFHI) has been implemented by WHO and Unicef with a view to protect, promote and support breast feeding. This paper aims to assess the influence of the BFHI on breastfeeding indicators in Brazil, using data from the 2nd Survey of Breastfeeding Prevalence, conducted in 2008. Methods Data on 64 municipalities were analysed: a total of 65 936 infants under the age of 1 year who were covered by the 2008 immunisation campaign. The outcomes of interest were breast feeding in the first hour of life in infants under 1 year of age; exclusive breast feeding on the first day after hospital discharge in infants under 4 months of age; exclusive breast feeding in infants under 2, 3 and 6 months of age; and pacifier use in infants under 6 months of age. The influence of birth in baby-friendly hospitals (BFHs) on these end points was analysed by means of Poisson regression with robust variance for complex samples. Findings Infants born in BFHs were 9% more likely to be breast fed in the first hour of life and 6% more likely to be breast fed on the first day at home. Exclusive breast feeding was 13%, 8% and 6% more likely in infants under the ages of 2, 3 and 6 months, respectively, born in BFHs. Birth in a BFH also correlated with significant less pacifier use. Conclusions The BFHI has had an impact on several indicators of breast feeding. The authors hope the results of this study will make policy makers and health professionals aware of the importance and potential of this strategy. [ABSTRACT FROM AUTHOR]

Background The relationship between childhood residential mobility and health in the UK is not well established; however, research elsewhere suggests that frequent childhood moves may be associated with poorer health outcomes and behaviours. The aim of this paper was to compare people in the West of Scotland who were residentially stable in childhood with those who had moved in terms of a range of health measures. Methods A total of 850 respondents, followed-up for a period of 20 years, were included in this analysis. Childhood residential mobility was derived from the number of addresses lived at between birth and age 18. Multilevel regression was used to investigate the relationship between childhood residential mobility and health in late adolescence (age 18) and adulthood (age 36), accounting for socio-demographic characteristics and frequency of school moves. The authors examined physical health measures, overall health, psychological distress and health behaviours. Results Twenty per cent of respondents remained stable during childhood, 59% moved one to two times and 21% moved at least three times. For most health measures (except physical health), there was an increased risk of poor health that remained elevated for frequent movers after adjustment for socio-demographic characteristics and school moves (but was only significant for illegal drug use). Conclusions Risk of poor health was elevated in adolescence and adulthood with increased residential mobility in childhood, after adjusting for sociodemographic characteristics and school moves. This was true for overall health, psychological distress and health behaviours, but physical health measures were not associated with childhood mobility. [ABSTRACT FROM AUTHOR]

Introduction As all published measures of dependence for users of smokeless tobacco (dippers) have poor reliability, in the present work the Hooked on Nicotine Checklist (HONC) and the Autonomy Over Smoking Scale (AUTOS) were evaluated for use with this population. Dippers and smokers were also compared in relation to dependence, the pleasure derived from using tobacco and the latency to the onset of withdrawal. Methods In 2010, an anonymous self-completed paper survey was administered to 1541 students of mixed race and ethnicity in grades 9-12 (mean age 15.9 years) in a Florida high school where students used cigarettes and smokeless tobacco. Results The reliability (Cronbach's α) for the HONC was 0.90 for smokers (n=139) and 0.91 for dippers (n=85), and for the AUTOS was 0.94 for smokers and dippers. Dippers and smokers did not differ significantly in relation to scores on the HONC, AUTOS, latency to withdrawal onset or pleasure derived from smoking. One or more symptoms on the HONC were reported by 56% of dippers and 57% of smokers with <100 lifetime uses of their favoured tobacco product, and by 91% of dippers and 91% of smokers with ≥100 lifetime uses (not significant). Greater lifetime use was associated with a significantly shorter latency to withdrawal for smokers and dippers. Conclusions The HONC and AUTOS are highly reliable measures of dependence for adolescent users of cigarettes and smokeless tobacco. Using these measures and other indicators, no meaningful differences in dependence were found between dippers and smokers at comparable levels of lifetime use. [ABSTRACT FROM AUTHOR]
