Evaluation of Community-Level Effects of Communities That Care on Adolescent Drug Use and Delinquency Using a Repeated Cross-Sectional Design.

ABSTRACT: The Communities That Care (CTC) prevention system has shown effects on reducing incidence and prevalence of problem behaviors among a panel of youth followed from 5th through 12th grade. The present report examines whether similar intervention effects could be observed using a repeated cross-sectional design in the same study. Data were from a community-randomized trial of 24 US towns. Cross-sectional samples of sixth, eighth, and tenth graders were surveyed at four waves. Two-stage ANCOVA analyses estimated differences between CTC and control communities in community-level prevalence of problem behaviors for each grade, adjusting for baseline prevalence. No statistically significant reductions in prevalence of problem behaviors were observed at any grade in CTC compared to control communities. Secondary analyses examined intervention effects within a “pseudo cohort” where cross-sectional data were used from sixth graders at baseline and tenth graders 4 years later. When examining effects within the pseudo cohort, CTC compared to control communities showed a significantly slower increase from sixth to tenth grade in lifetime smokeless tobacco use but not for other outcomes. Exploratory analyses showed significantly slower increases in lifetime problem behaviors within the pseudo cohort for CTC communities with high, but not low, prevention program saturation compared to control communities. Although CTC demonstrated effects in a longitudinal panel from the same community-randomized trial, we did not find similar effects on problem behaviors using a repeated cross-sectional design. These differences may be due to a reduced ability to detect effects because of potential cohort effects, accretion of those who were not exposed, and attrition of those who were exposed to CTC programming in the repeated cross-sectional sample.

Project description:Objective: This study aimed to investigate the level of haze-related knowledge adolescents have and to explore relevant influencing factors. Methods: From June 2015 to January 2016, researchers randomly selected 2 districts from the 20 districts of Baoding, China. Then, researchers randomly selected two middle schools from two districts. By conducting a stratified cluster sampling and considering one class as a unit, researchers randomly selected, from the other middle school, five first-grade classes, five second-grade classes, five third-grade classes from the one middle school, and three first-grade classes, two second-grade classes, and two third-grade classes. Finally, 1,100 adolescents were investigated by using the demographic questionnaire and the Adolescent Haze-Related Knowledge Awareness Assessment Scale (AHRKAAS). Multiple linear regressions were conducted to explore factors affecting the adolescent haze-related knowledge. Sensitivity analysis was used to confirm associations between influencing factors and AHRKAAS scores. Results: The AHRKAAS score rate was 69.9%. The dimension of human factors of haze formation was the highest (score rate = 85.6%). The dimension of haze harms on the human body was the lowest (score rate = 57.1%). Compared with the group (monthly expenses <300 yuan), the group (monthly expenses ≥ 600 yuan) had a higher AHRKAAS score (β = 4.882, 95% CI: 0.979, 8.784). Compared with the group (Do not live with parents), the group (Live with parents) had a higher AHRKAAS score (β = 14.675, 95% CI: 9.494, 19.855). Compared with the group (Never undergo a physical examination), the group (Once a year) (β = 7.444, 95% CI: 2.922, 11.966) and the group (A few times a year) (β = 7.643, 95% CI: 2.367, 12.919) had a higher AHRKAAS score. Compared with the group (Know nothing), the group (Know most) (β = 9.623, 95% CI: 2.929, 16.316) and the group (Know very well) (β = 15.367, 95% CI: 7.220, 23.515) had a higher AHRKAAS score. These associations were still reliable and consistent in different sensitivity analysis models. Conclusion: The level of adolescent haze-related knowledge is low and is affected by monthly expenses, living condition, physical examination frequency, and knowledge of respiratory system diseases. Government bodies, schools, and research institutions should strengthen cooperation of health publicity and health education to improve adolescent haze-related knowledge.

Project description:OBJECTIVE:The study aimed to identify the effects of the individual-level and community-level factors on the use of family planning (FP) among married women in the pastoralist community of Ethiopia. DESIGN:A community-based cross-sectional study was conducted in September 2018. Data were analysed using R software. To determine the fixed effect of individual-level and community-level factors of FP use, a two-level mixed-effects logistic regression was used. The result was described using the Adjusted OR (AOR), and the variance partition coefficient. SETTING AND PARTICIPANTS:Afar, Ethiopia (2018; n=891) married women of reproductive age (15-49) years. PRIMARY OUTCOME MEASURES:FP use or non-use. RESULTS:The current use of FP was 18.7% (16.31%-21.43%). Women who need to walk 1?hour and more to the nearest health facility (AOR 0.14, 95% CI 0.05 to 0.3), have ANC visit of 4 and above (AOR 6.02, 95% CI 1.74 to 20.8), had their last birth at a health facility (AOR 2.71 95%?CI 1.27 to 5.81), have five and more children (AOR 4.71, 95%?CI 1.86 to 11.9), have high knowledge on FP (AOR 2.74, 95% CI 1.11 to 6.74) and had high intentions to use FP (AOR 10.3, 95%?CI 3.85 to 27.6) were more likely to report FP use. The magnitude of the effect of for FP use was smaller than that of 9 of the 13 individual factors. Apart from this 19.4% of the total variance in the odds of using FP attributed to between community difference (intraclass correlation coefficient=0.194). Regarding the community-level characteristics, clusters of having higher electronic media possession (AOR 2.84, 95%?CI 1.2 to 6.72) and higher women decision making on FP (AOR 8.35, 95%?CI 2.7 to 27.1) were significantly associated with increased FP use compared with clusters with lower reports of these aspects. CONCLUSION:FP use among the pastoralist community is influenced by both individual cluster/community-level characteristics or factors. Even though the effect of clustering in FP use was large in comparison with the unexplained between-cluster variation, it was lower than the individual-level factors.

Project description:BACKGROUND:An adverse drug reaction (ADR) is a response to a medicine that is not intended and is harmful, and which occurs at normal dose levels for humans. Currently, there are no estimates of the population-based prevalence of ADRs in the Kingdom of Saudi Arabia (KSA). OBJECTIVE:The aims of this study were to (1) estimate the population-based prevalence of ADRs in KSA, (2) describe the ADRs experienced by survey respondents, and (3) investigate the level of awareness of the ADR reporting system. PATIENTS AND METHODS:This was a cross-sectional survey using stratified, population-based sampling conducted at a chain of community pharmacies. RESULTS:Analysis was conducted on 5228 surveys; 50.17% of respondents were males, and the mean age was 39?±?15 years (min?=?18, max?=?98). The sample prevalence of ADRs was 23.45% (95% CI 22.30-24.60%, P?<?0.001). The estimated population prevalence (after weighting) was 28.00% (26.10-30.00%). Gastrointestinal disorders were the most commonly reported ADRs (58.73%), followed by general disorders and administration site conditions (19.74%). The largest drug class that was reported to lead to ADRs was nonsteroidal anti-inflammatory drugs (NSAIDs) (11%). Over 19% of the respondents who experienced an ADR required medical intervention to control the suffering induced by the ADR. Of the respondents who experienced an ADR, 371 (30.26%) were aware of the ADR reporting system but only 53 (14.29%) said that they had filed a report in the system. CONCLUSIONS:Our study estimated that 28% of the population experienced an ADR over a 1-year period in KSA. Risk factors for ADR included certain chronic disease groups and the use of certain classes of medications. Regulatory authorities in KSA intend to conduct more research and deploy educational interventions to reduce ADR rates in KSA. This will hopefully occur in an international context that promotes the standardized measurement of ADRs in the community. A subset of findings from this report was presented in an oral presentation at the Saudi Food and Drug Authority (SFDA) Annual Conference, September 27, 2018. In addition, a subset of findings from this report were presented on a poster at the International Conference of Pharmacoepidemiology and Therapeutic Risk Management (ICPE), August 27, 2019.

Project description:Adolescent use of marijuana is associated with adverse later effects, so the identification of factors underlying adolescent use is of substantial public health importance. The relationship between US state laws that permit marijuana for medical purposes and adolescent marijuana use has been controversial. Such laws could convey a message about marijuana acceptability that increases its use soon after passage, even if implementation is delayed or the law narrowly restricts its use. We used 24 years of national data from the USA to examine the relationship between state medical marijuana laws and adolescent use of marijuana.Using a multistage, random-sampling design with replacement, the Monitoring the Future study conducts annual national surveys of 8th, 10th, and 12th-grade students (modal ages 13-14, 15-16, and 17-18 years, respectively), in around 400 schools per year. Students complete self-administered questionnaires that include questions on marijuana use. We analysed data from 1?098?270 adolescents surveyed between 1991 and 2014. The primary outcome of this analysis was any marijuana use in the previous 30 days. We used multilevel regression modelling with adolescents nested within states to examine two questions. The first was whether marijuana use was higher overall in states that ever passed a medical marijuana law up to 2014. The second was whether the risk of marijuana use changed after passage of medical marijuana laws. Control covariates included individual, school, and state-level characteristics.Marijuana use was more prevalent in states that passed a medical marijuana law any time up to 2014 than in other states (adjusted prevalence 15·87% vs 13·27%; adjusted odds ratio [OR] 1·27, 95% CI 1·07-1·51; p=0·0057). However, the risk of marijuana use in states before passing medical marijuana laws did not differ significantly from the risk after medical marijuana laws were passed (adjusted prevalence 16·25% vs 15·45%; adjusted OR 0·92, 95% CI 0·82-1·04; p=0·185). Results were generally robust across sensitivity analyses, including redefining marijuana use as any use in the previous year or frequency of use, and reanalysing medical marijuana laws for delayed effects or for variation in provisions for dispensaries.Our findings, consistent with previous evidence, suggest that passage of state medical marijuana laws does not increase adolescent use of marijuana. However, overall, adolescent use is higher in states that ever passed such a law than in other states. State-level risk factors other than medical marijuana laws could contribute to both marijuana use and the passage of medical marijuana laws, and such factors warrant investigation.US National Institute on Drug Abuse, Columbia University Mailman School of Public Health, New York State Psychiatric Institute.
