The relationship between age of smoking initiation and current smoking: an analysis of school surveys in three European countries.

INTRODUCTION: It is held that younger smoking initiates are more likely to become regular smokers. The definitions of smoking initiation (a puff, part of a cigarette, a whole cigarette) are inconsistent and raise questions about the robustness of the view. We sought to re-examine the relationship using adolescent smoking data from 3 European countries. METHODS: A stratified secondary, logistic regression analysis of Global Youth Tobacco Survey data was conducted using a design-based analysis. Subgroup analyses were conducted of 13- to 15-year olds from Latvia (high smoking prevalence), Slovenia (moderate prevalence), and Montenegro (low prevalence) who had initiated smoking. The outcome was current smoking--smoking everyday for the past 30 days, or smoking 10 or more days in the past 30 days. Smoking initiation was operationalized as a single puff of a cigarette, and age of smoking initiation was a derived continuous measure. RESULTS: In Latvia, there was a significant association between age of smoking initiation and current smoking for males (p < .05) and females (p < .001) when smoking was operationalized as smoking every day. It was only significant in female adolescents (p < .001) for smoking 10 or more days. In Slovenia and Montenegro, there was no significant relationship between age of smoking initiation and current smoking for either males or females. CONCLUSIONS: The evidence about the relationship between age of smoking initiation and current smoking is not clear. Explanations for the findings may relate to a lack of power, the specificity of the measure, or problems with the theory.

Secondhand tobacco smoke exposure in selected public places (PM2.5 and air nicotine) and non-smoking employees (hair nicotine) in Ghana.

BACKGROUND: Secondhand tobacco smoke (SHS) exposure is a global public health problem. Ghana currently has no legislation to prevent smoking in public places. To provide data on SHS levels in hospitality venues in Ghana the authors measured (1) airborne particulate matter <2.5 µm (PM(2.5)) and nicotine concentrations and (2) hair nicotine concentrations in non-smoking employees. Quantifying SHS exposure will provide evidence needed to develop tobacco control legislation. METHOD: PM(2.5) was measured for 30 min in 75 smoking and 13 non-smoking venues. Air nicotine concentrations were measured for 7 days in 8 smoking and 2 non-smoking venues. Additionally, 63 non-smoking employees provided hair samples for nicotine analysis. RESULT: Compared to non-smoking venues, smoking venues had markedly elevated PM(2.5) (median 553 [IQR 259-1038] vs 16.0 [14.0-17.0]µg/m(3)) and air nicotine (1.83 [0.91-4.25] vs 0.03 [0.02-0.04]µg/m(3)) concentrations. Hair nicotine concentrations were also higher in non-smoking employees working in smoking venues (median 2.49 [0.46-6.84] ng/mg) compared to those working in non-smoking venues (median 0.16 [0.08-0.79]ng/mg). Hair nicotine concentrations correlated with self-reported hours of SHS exposure (r=0.35), indoor air PM(2.5) concentrations (r=0.47) and air nicotine concentrations (r=0.63). CONCLUSION: SHS levels were unacceptably high in public places in Ghana where smoking is allowed, despite a relatively low-smoking prevalence in the country. This is one of the first studies to ascertain SHS and hair nicotine in Africa. Levels were comparable to those measured in American, Asian and European countries without or before smoking bans. Implementing a comprehensive smoke-free legislation that protects workers and customers from exposure to secondhand smoke is urgently needed in Ghana.

Feasibility and acceptability of the use of artemether-lumefantrine in the home management of uncomplicated malaria in children 6-59 months old in Ghana.

OBJECTIVE: We assessed the feasibility and acceptability of and the willingness to use artemether-lumefantrine (Coartem) during early, appropriate treatment of malaria/fever in children aged 6-59 months at the community and household level in a rural malaria-endemic area in Ghana. METHOD: In this descriptive study with a pre- post-evaluation of an intervention, community perceptions of fever, health-seeking behaviour and current treatment practices for children aged 6-59 months were ascertained through qualitative research and surveys. The children were counted in a household census and given identification cards. Community-based agents (who were supervised monthly) dispensed a 6-dose-treatment formulation of Coartem over a 4 months period and counseled caregivers on case management and referral. Caregivers who consulted were followed up after 4 days to determine adherence to the treatment regimen. Blister packs of the drugs were inspected where available. The performance of the agents in terms of counselling, advising on referral and reporting was evaluated. Community satisfaction was also assessed qualitatively through focus group discussions and interviews. RESULTS: Three hundred and sixty-three children sought care during the intervention period. All 235 children aged 6-35 months were correctly provided the one tablet per dose per treatment package compared with 119 of 125 children 36-59 months (95.2%). Only 5 of 17 children were referred appropriately. All 334 caregivers followed the correct drug administration schedule, i.e. twice a day for 3 days. Validation of drugs received indicates that all 204 children aged 6-35 months and 103/118 (87.3%) children aged 36-59 months received the correct drug dose. Adherence of agents and caregivers to the treatment was 308/334 (92.5%). Delay in seeking care was reduced from 3 to 2 days. No serious adverse drug reactions were reported. Community members were enthusiastic about the performance of the agents. CONCLUSION: A Home Management of Malaria (HMM) strategy with Coartem using trained community-based agents supervised monthly is feasible, acceptable, and can achieve high levels of compliance within Dangme, West District of Ghana. However, if the intervention is to be sustainable, the agents need to be paid.
