Tobacco-free School Training Program for Teachers and Tobacco-use among Adolescent Students in the Rural Indian Context: A Quasi-experimental Study

BackgroundGhana faces an increasing burden of non-communicable disease with rates of hypertension estimated as high as 36% in adults. Despite these high rates, hypertension control remains very poor in Ghana (4%). The current project aims to implement and evaluate a community-based programme to raise awareness, and to improve treatment and control of hypertension in the Eastern Region of Ghana. In this paper, we present the findings of the baseline cross-sectional survey focusing on hypertension prevalence, awareness, treatment, and control.MethodsTo evaluate the ComHIP project, a quasi-experimental design consisted of a before and after evaluations are being implemented in the intervention and comparison districts. A cohort study component is being implemented in the intervention district to assess hypertension control. Background anthropometric and clinical data collected as part of the baseline survey were analyzed in STATA Version 11. We examined the characteristics of individuals, associated with the baseline study outcomes using logistic regression models.ResultsWe interviewed 2400 respondents (1200 each from the comparison and intervention districts), although final sample sizes after data cleaning were 1170 participants in the comparison district and 1167 in the intervention district. With the exception of ethnicity, the control and intervention districts compare favorably. Overall 32.4% of the study respondents were hypertensive (31.4% in the control site; and 33.4% in the intervention site); 46.2% of hypertensive individuals were aware of a previous diagnosis of hypertension (44.7% in the control site, and 47.7% in the intervention site), and only around 9% of these were being treated in either arm. Hypertension control was 1.3% overall (0.5% in the comparison site, and 2.1% in the intervention site). Age was a predictor of having hypertension, and so was increasing body mass index (BMI), waist, and hip circumferences. After adjusting for age, the risk factors with the greatest association with hypertension were being overweight (aOR = 2.30; 95% CI 1.53–3.46) or obese (aOR = 3.61; 95% CI 2.37–5.51). Older individuals were more likely to be aware of their hypertension status than younger people. After adjusting for age people with a family history of hypertension or CVD, or having an unhealthy waist hip ratio, were more likely to be aware of their hypertension status.ConclusionsThe high burden of hypertension among the studied population, coupled with high awareness, yet very low level of hypertension treatment and control requires in-depth investigation of the bottlenecks to treatment and control. The low hypertension treatment and control rates despite current and previous general educational programs particularly in the intervention district, may suggest that such programs are not necessarily impactful on the health of the population.

BackgroundSeasonal malaria chemoprevention (SMC) is a new strategy recommended by WHO in areas of highly seasonal transmission in March 2012. Although randomized controlled trials (RCTs) have shown SMC to be highly effective, evidence and experience from routine implementation of SMC are limited.MethodsA non-randomized pragmatic trial with pre-post design was used, with one intervention district (Kita), where four rounds of SMC with sulfadoxine + amodiaquine (SP + AQ) took place in August–November 2014, and one comparison district (Bafoulabe). The primary aims were to evaluate SMC coverage and reductions in prevalence of malaria and anaemia when SMC is delivered through routine programmes using existing community health workers. Children aged 3–59 months from 15 selected localities per district, sampled with probability proportional to size, were surveyed and blood samples collected for malaria blood smears, haemoglobin (Hb) measurement, and molecular markers of drug resistance in two cross-sectional surveys, one before SMC (July 2014) and one after SMC (December 2014). Difference-in-differences regression models were used to assess and compare changes in malaria and anaemia in the intervention and comparison districts. Adherence and tolerability of SMC were assessed by cross-sectional surveys 4–7 days after each SMC round. Coverage of SMC was assessed in the post-SMC survey.ResultsDuring round 1, 84% of targeted children received at least the first SMC dose, but coverage declined to 67% by round 4. Across the four treatment rounds, 54% of children received four complete SMC courses. Prevalence of parasitaemia was similar in intervention and comparison districts prior to SMC (23.4 vs 29.5%, p = 0.34) as was the prevalence of malaria illness (2.4 vs 1.9%, p = 0.75). After SMC, parasitaemia prevalence fell to 18% in the intervention district and increased to 46% in the comparison district [difference-in-differences (DD) OR = 0.35; 95% CI 0.20–0.60]. Prevalence of malaria illness fell to a greater degree in the intervention district versus the comparison district (DD OR = 0.20; 95% CI 0.04–0.94) and the same for moderate anaemia (Hb < 8 g/dL) (DD OR = 0.26, 95% CI 0.11–0.65). The frequency of the quintuple mutation (dhfr N51I, C59R and S108N + dhps A437G and K540E) remained low (5%) before and after intervention in both districts.ConclusionsRoutine implementation of SMC in Mali substantially reduced malaria and anaemia, with reductions of similar magnitude to those seen in previous RCTs. Improving coverage could further strengthen SMC impact.Trial registration clinical trial registration number NCT02894294

Position Statement on Tobacco Exposures in Children and Families

BackgroundLack of improved sanitation is the most important contributing factor to diarrheal disease among under-five children in low and middle-income countries. There was no study to identify the effect of Community-Led Total Sanitation and Hygiene intervention on diarrheal diseases in the study area. Hence, this study was designed with the aim of finding the effects of Community-led Total Sanitation and Hygiene implementation for preventing diarrhea among under-five children.MethodsA community-based Quasi-Experimental study was conducted among a sample of 846 households selected from intervention (kersa) and comparison (mana) districts using the four-stage random cluster-sampling method. A Semi-structured questionnaire was used to collect data. The collected data was cleaned, coded, and entered into EpiData version 3.1 and exported to SPSS version 20 for analysis. Difference-in Difference method with McNemar’s tests was used to compare the prevalence of diarrhea between the intervention and comparison districts, and the significance of change between the pre-test and post-test was declared at p-value less than 0.05 with 95% confidence interval.ResultsThe intervention led to decreased diarrhea prevalence [pp = -8.2, 95% CI: -15.9, -0.5], increased latrine ownership [pp = 5.6, 95% CI: 0.5, 10.8], and increased latrine utilization [pp = 10.7, 95% CI: 4.7, 16.6] in intervention district at post-test compared to the baseline; while the presence of handwashing facility near the latrine, home-based water treatment, and proper water storage and handling practice were decreased at post-test compared to the baseline.ConclusionImplementation of Community-Led Total Sanitation improved sanitation and hygiene status of community that resulted in the reduction of diarrhea diseases in under-five children. Further implementation, evaluation, and scale-up of the interventions are needed to reduce diarrheal disease in under-five children.

Effect of seasonal malaria chemoprevention in children between 5 and 9 years old in Kita and Bafoulabe districts, Mali

Although abortion became legal in India in 1971, many women are unaware of the law. Behavior change communication interventions may be an effective way to promote awareness of the law and change knowledge of and perceptions about abortion, particularly in settings in which abortion is stigmatized. To evaluate the effectiveness of a behavior change communication intervention to improve women's knowledge about India's abortion law and their perceptions about abortion, a quasi-experimental study was conducted in intervention and comparison districts in Bihar and Jharkhand. Household surveys were administered at baseline in 2008 and at follow-up in 2010 to independent, randomly selected cross-sectional samples of rural married women aged 15-49. Logistic regression difference-in-differences models were used to assess program effectiveness. Analysis demonstrated program effectiveness in improving awareness and perceptions about abortion. The changes in the odds of knowing that abortion is legal and where to obtain safe abortion services were larger between baseline and follow-up in the intervention districts than the changes in odds observed in the comparison districts (odds ratios, 16.1 and 1.9, respectively). Similarly, the increase in women's perception of greater social support for abortion within their families and the increase in perceived self-efficacy with respect to family planning and abortion between baseline and follow-up was greater in the intervention districts than in the comparison districts (coefficients, 0.17 and 0.18, respectively). Behavior change communication interventions can be effective in improving knowledge of and perceptions about abortion in settings in which lack of accurate knowledge hinders women's access to safe abortion services. Multiple approaches should be used when attempting to improve knowledge and perceptions about stigmatized health issues such as abortion.

IntroductionMost tobacco use begins in adolescence, causing dependence and prolonged use, and accounts for more than 8 million deaths worldwide annually. Monitoring adolescent tobacco use is critical to controlling it. Our study examined the prevalence and factors associated with tobacco use among adolescents in Nigeria.MethodsWe conducted a descriptive cross-sectional study among adolescent students in Ibadan, Nigeria, aged 11 to 18 years, from March through June 2021. We used a 2-stage cluster design to select 3,199 students from 23 schools. We adapted the Global Youth Tobacco Survey Core Questionnaire, version 1.2, for data collection and used logistic regression to assess factors associated with current tobacco use. We weighted all analyses for complex survey design and differential nonresponse at school, class, and student levels.ResultsPrevalence of current use of cigarettes, smokeless tobacco, or any tobacco were 1.4%, 1.1%, and 2.0%, respectively. Predictors of current tobacco use were male sex (adjusted odds ratio [aOR] = 3.13; 95% CI, 1.53–6.42); close friends as smokers (aOR = 3.10; 95% CI, 1.77–5.41); classmates as smokers (aOR = 3.12; 95% CI, 1.15–8.49); access to cigarette (aOR = 6.65; 95% CI, 2.55–17.33); perception that smoking is attractive (aOR = 3.15; 95% CI, 1.17–8.44); exposure to secondhand smoke (aOR = 2.93; 95% CI, 1.07–8.03); and internet awareness of tobacco use (aOR = 3.22; 95% CI, 1.48–7.04).ConclusionPrevalence of adolescent tobacco use was low in Ibadan. Predictors were peer influence, access to cigarettes, misperceptions about tobacco use, exposure to secondhand smoke, and tobacco advertising. We recommend an antitobacco campaign that uses a peer education strategy, a comprehensive enforcement of tobacco advertising, and a ban on public smoking.

Universal coverage with effective vector control remains the mainstay of malaria vector control in sub-Saharan Africa. Tanzania has utilized a number of mechanisms for the maintenance of long-lasting insecticidal net (LLIN) coverage over time. Schools have been identified as one potential channel for continuous distribution of LLIN. This research aims to evaluate an annual school-based LLIN distribution programme in Tanzania that began in 2013, called the School Net Programme (SNP). Following each of the first four rounds of SNP distribution, a household survey was conducted in intervention and comparison districts in Southern and Lake zones of Tanzania (N = 5083 households). Measures of ownership, access and use were compared between intervention and comparison districts. Determinants of reach were assessed in intervention districts. Population access to an LLIN increased from 63.1% (95% CI: 58.8, 67.5) to 76.5% (95% CI: 72.9, 80.0) in the intervention districts between the first and last surveys. Access also rose in the comparison districts from 51.4% (95% CI: 46.9, 55.9) to 79.8% (95% CI: 77.3, 82.0) following mass distribution and implementation of school-based distribution during the study period. LLIN use increased in intervention districts from 44.9% (95% CI: 40.5, 49.3) to 65.6% (95% CI: 59.4, 71.8) and from 57.2% (95% CI: 49.7, 64.7) to 77.4% (95% CI: 69.3, 85.5) specifically amongst primary school-aged children. Households reached by the SNP were wealthier households with children enrolled in school. The SNP in Tanzania was able to maintain population level LLIN ownership, use and access in the absence of mass distribution. The SNP successfully reached households that housed school-aged children. Alternative delivery strategies may need to be considered to reach households without children enrolled in schools that experienced fewer benefits from the programme.

Tobacco use and second-hand smoke exposure in young adolescents aged 12-15 years: data from 68 low-income and middle-income countries.

Socio-economic disparities in health have been well documented around the world. This study examines whether NGO facilitation of the government's community-based health programme improved the equity of maternal and newborn health in rural Uttar Pradesh, India. A quasi-experimental study design included one intervention district and one comparison district of rural Uttar Pradesh. A household survey conducted between January and June 2003 established baseline rates of programme coverage, maternal and newborn care practices, and health care utilization during 2001-02. An endline household survey was conducted after 30 months of programme implementation between January and March 2006 to measure the same indicators during 2004-05. The changes in the indicators from baseline to endline in the intervention and comparison districts were calculated by socio-economic quintiles, and concentration indices were constructed to measure the equity of programme indicators. The equity of programme coverage and antenatal and newborn care practices improved from baseline to endline in the intervention district while showing little change in the comparison district. Equity in health care utilization for mothers and newborns also showed some improvements in the intervention district, but notable socio-economic differentials remained, with the poor demonstrating less ability to access health services. NGO facilitation of government programmes is a feasible strategy to improve equity of maternal and neonatal health programmes. Improvements in equity were most pronounced for household practices, and inequities were still apparent in health care utilization. Furthermore, overall programme coverage remained low, limiting the ability to address equity. Programmes need to identify and address barriers to universal coverage and care utilization, particularly in the poorest segments of the population.

Implementation and evaluation of the Reaching Every District (RED) strategy in Assam, India, 2005–2008

Background: Reducing maternal and perinatal mortality in sub Saharan Africa remains challenging and requires effective and context specific interventions.Objective: The aims of this paper were to demonstrate the impact of the community mobilisation of the Skilled Care Initiative (SCI) in reducing maternal and perinatal mortality and to describe the concept and implementation in order to guide replication and scaling up.Designs: A quasi experimental design was used to assess the extent to which the SCI was associated with increased institutional births, maternal and perinatal mortality reduction in an intervention (Ouargaye) versus a comparison (Diapaga) district. A geo-referenced census was conducted to retrospectively assess changes in outcomes and process measures. A detailed description of activities, rationale and timing of implementation were gathered from the SCI project officers and summarised. Data analyses included descriptive statistics and multivariate analyses.Results: At macro level, the main significant difference between Ouargaye and Diapaga districts was the scope and intensity of the community-based interventions implemented in Ouargaye. There was a temporal association relationship before and after the implementation of the demand-driven interventions and a remarkable 30% increase in institutional births in the intervention district compared to 10% increase in comparison district. There was a significant reduction of perinatal mortality rates (OR =0.75, CI 0.70–0.80) in intervention district and a larger decrease in maternal mortality ratios in intervention district, although statistical significance was not reached. A comprehensive framework of community mobilisation strategy is proposed to improve maternal and child health in poorest communities.Conclusion: Controlling for the availability and quality of health services, working in partnership and effectively with communities, and not for them – hence characterising communities as not being empty vessels – can have impacts on outcomes. Here, in the district with a community mobilisation programme, there was a marked increase in institutional births and reductions in maternal and perinatal deaths.

BackgroundChildhood immunisation is one of the most cost-effective public health interventions, preventing 4–5 million deaths annually. This study assessed the prevalence and determinants of zero-dose immunisation among children aged 12–35 months in conflict-affected districts implementing Ethiopia’s Productive Safety Net Programme (PSNP) to determine whether intervention and comparison areas are comparable before rollout of the enhanced service-integration model.MethodsA comparative cross-sectional survey was conducted among 4,099 mothers and caregivers of children aged 12-35 months in intervention and comparison PSNP districts. Data were collected using a structured questionnaire administered by trained enumerators. Multivariable logistic regression was used to identify factors associated with zero-dose status.ResultsZero-dose prevalence was 30% in intervention districts and 27% in comparison districts, with notable regional disparities: 22.5% in Amhara, 23% in Afar, and 39% in Tigray. Vaccination dropout showed a different pattern, with the highest rate in Afar (57.6%) and the lowest in Tigray (13.6%). DTP3 coverage was lowest in Afar (42.9%) and highest in Amhara (69.4%), while MCV1 coverage was highest in Tigray (83.8%), followed by Amhara (79.6%) and Afar (49.1%). In intervention districts, zero-dose status was significantly associated with region (AOR = 1.5; 95% CI: 1.1–2.2), lack of maternal education (AOR = 1.7; 95% CI: 1.1–2.7), unmarried status (AOR = 1.8; 95% CI: 1.0–3.2), older child age (24–35 months) (AOR = 3.7; 95% CI: 2.6–5.3), and longer distance to health facilities (AOR = 1.4; 95% CI: 1.0–2.2). In comparison districts, region, maternal education, and older child age remained significant predictors.ConclusionsThe study highlights persistent inequities in immunisation coverage in conflict-affected settings. It also demonstrates comparability between intervention and comparison PSNP districts in zero-dose prevalence and its determinants. These baseline findings provide a foundation for attributing future post-intervention improvements to enhanced integration of health services within the PSNP framework.

Introduction: Comprehensive tobacco-free school policy benefits everyone by reducing exposure to second-hand smoking and creating a system that reinforces tobacco-free norm and attitudes, which in turn affect tobacco use having an impact on the health of the community. Objective: This study aims to assess the perception of teachers on tobacco free school environments and factors supporting it. Methods: A two-stage cluster sampling technique was used for the selection of schools with selection probability proportional to enrolment size followed by stratified random sampling of government and private schools. Data were collected from 559 secondary school teachers using a structured questionnaire.Results: Estimation indicated that 48.3% (95% CI: 44.5%, 52.6%) of the teachers were less supportive and 51.7% (95% CI: 47.4%, 55.5%) were more supportive for smoking free school. Logistic regression analysis revealed that non tobacco user teachers were more likely to be supportive (OR=1. 891, 95% CI: 1.197, 2.986) for tobacco free school. However, no statistically significant association was found between perceived supportive tobacco free school and age, sex, level of education, type of school and family size (p&gt;0.05). Exposure to second hand smoking and curriculum content of tobacco issues were not significantly related with tobacco free school.Conclusion: Comprehensive school based programme with participation of school personnel and community can effectively implement tobacco free school programmes.Bangladesh Journal of Medical Science Vol.14(3) 2015 p.274-279
