Cigarette smoking and reasons for leaving school among school dropouts in South Africa.

BACKGROUND: School dropouts are at heightened risk of tobacco use compared to in-school learners. School dropouts are described as those not currently enrolled in school for the academic year, have not completed their schooling, and are between 13 and 20 years old. This paper examines the relationship between reasons for leaving school and past month cigarette smoking, taking into account gender differences. METHODS: Multiple logistic regression was used to analyse survey data (n = 4185). Geographical location was also incorporated into the analysis as effect moderators. RESULTS: Although no significant main effects between reasons for leaving school and tobacco use were found, results showed that those who leave school early smoke more. When examining interaction effects with gender, leaving school due to 'not being able to pay for school fees' was significantly associated with smoking, but only among girls residing in urban areas (OR = 0.327, p = .023). CONCLUSIONS: More research is needed to understand why learners leave school and their subsequent tobacco use. This knowledge will help researchers identify and target those students that are at risk for dropping out of school and using tobacco.

Age at the onset of tobacco smoking in South Africa: a discrete-time survival analysis of the prognostic factors.

BACKGROUND: While knowledge of onset of smoking tobacco, and associated risk factors can aid the formulation of evidence-based policy and interventions, such information is scarce in South Africa. We assessed age at onset of tobacco smoking in South Africa and identified its risk factors. METHODS: We analysed data of 15,316 respondents aged 15-98 years from the 2012 South African National Health and Nutrition Examination Survey. Descriptive statistics and survival analysis techniques were used alongside weighted percentages. RESULTS: Overall lifetime prevalence of smoking was 20.5%. Among the 3360 ever-smoked respondents, the overall median age at smoking onset was 18 years (Inter-quartile range (IQR) =5) with 2% starting before age 10 while 60% had smoked before age 20. Likelihood of tobacco smoking was higher among adolescents (<=20 years) and those aged 20-29 years than those aged > = 60 years, thrice higher among males, 29% higher among urban dwellers and thrice higher in Western Cape and Free State than in North West Province. The onset of tobacco smoking was earlier among males, wealthier and "coloured" people from Northern and Eastern Capes. CONCLUSION: The onset of tobacco smoking peaked at 15-22 years and varied by province, sex, location, race and other characteristics. The age restrictions on smoking in South Africa has changed over time, coupled with the recent open and electronic advertisement of tobacco, and social media could have influenced the earlier onset of tobacco smoking in South Africa. Stricter regulations on tobacco-related advertisement and sales should be implemented.

Social network determinants of alcohol and tobacco use: A qualitative study among out of school youth in South Africa.

An important determinant of alcohol and tobacco use is the adolescent's social network, which has not been explored among out of school youth (OSY). OSY are adolescents not currently enrolled in school and have not completed their schooling. This study aims to qualitatively understand how OSY's social networks support or constrain alcohol and tobacco use. Respondent-driven sampling was used to select 41 OSY (aged 13-20 years) for individual in-depth interviews in a South African urban area. The data were analysed using content analysis. Smoking and drinking friends, family close in age to OSY that drank and smoked, and lack of parental support were associated with alcohol and tobacco use among OSY. Household norms, romantic partners and non-smoking or non-drinking friends were suggested to mitigate alcohol and tobacco use. Understanding how the social network of OSY plays a role in alcohol and tobacco use is useful for gaining an insight into the profile of OSY at risk for alcohol and tobacco use. Registration of OSY youth and community-based peer led programmes that include influential OSY family and friends could be beneficial.

"You Travel Faster Alone, but Further Together": Learning From a Cross Country Research Collaboration From a British Council Newton Fund Grant.

Providing universal health coverage (UHC) through better maternal, neonatal, child and adolescent health (MNCAH) can benefit both parties through North-South research collaborations. This paper describes lessons learned from bringing together early career researchers, tutors, consultants and mentors from the United Kingdom, Kenya, and South Africa to work in multi-disciplinary teams in a capacity-building workshop in Johannesburg, co-ordinated by senior researchers from the three partner countries. We recruited early career researchers and research users from a range of sectors and institutions in the participating countries and offered networking sessions, plenary lectures, group activities and discussions. To encourage bonding and accommodate cross-cultural and cross-disciplinary partners, we asked participants to respond to questions relating to research priorities and interventions in order to allocate them into multidisciplinary and cross-country teams. A follow up meeting took place in London six months later. Over the five day initial workshop, discussions informed the development of four draft research proposals. Intellectual collaboration, friendship and respect were engendered to sustain future collaborations, and we were able to identify factors which might assist capacity-building funders and organizers in future. This was a modestly funded brief intervention, with a follow-up made possible through the careful stewardship of resources and volunteerism. Having low and middle-income countries in the driving seat was a major benefit but not without logistic and financial challenges. Lessons learned and follow-up are described along with recommendations for future funding of partnerships schemes.

Note on generalized Mittag-Leffler function.

The present paper deals with the study of a generalized Mittag-Leffler function and associated fractional operator. The operator has been discussed in the space of Lebesgue measurable functions. The composition with Riemann-Liouville fractional integration operator has been obtained.
