RESUMO

BACKGROUND: Despite the negative impact of chronic school absenteeism on the psychological and physical health of adolescents, data on the burden of adolescent chronic school absenteeism (ACSA) and interventions and programs to address it are lacking. We estimated the global, regional and national level prevalence of ACSA and its correlation with violence and unintentional injury, psychosocial, protective, lifestyle, and food security-related factors among in-school adolescents across low and middle-income, and high-income countries (LMICs-HICs). OBJECTIVES: This study aimed to estimate the prevalence of chronic school absenteeism (CSA) as well as to determine its associated factors among in-school adolescents across 71 low-middle and high-income countries. METHODS: We used data from the most recent Global School-based Student Health Survey of 207,107 in-school adolescents aged 11-17 years in 71 LMICs-HICs countries across six WHO regions. We estimated the weighted prevalence of ACSA from national, regional and global perspectives. Multiple binary logistic regression analyses were used to estimate the adjusted effect of independent factors on ACSA. RESULTS: The overall population-weighted prevalence of CSA was 11·43% (95% confidence interval, CI: 11·29-11·57). Higher likelihood of CSA was associated with severe food insecurity, peer victimisation, loneliness, high level of anxiety, physically attack, physical fighting, serious injury, poor peer support, not having close friends, lack of parental support, being obese, and high levels of sedentary behaviours. Lower likelihood of CSA was associated with being female (odds ratio, OR = 0·76, 95% CI: 0·74-0·78). CONCLUSION: Our findings indicate that a combination of different socio-economic factors, peer conflict and injury factors, factors exacerbate CSA among adolescents. Interventions should be designed to focus on these risk factors and should consider the diverse cultural and socioeconomic contexts.

RESUMO

Objectives: The highly transmissible COVID-19 Delta variant (DV) has contributed to a surge in cases and exacerbated the worldwide public health crisis. Several COVID-19 vaccines play a significant role in a high degree of protection against the DV. The primary purpose of this meta-analysis is to estimate the pooled effectiveness of the COVID-19 vaccines against the DV in terms of risk ratio (RR) among fully vaccinated, compared to unvaccinated populations. Methods: We carried out a systematic review, with meta-analysis of original studies focused on COVID-19 vaccines effectiveness against a DV clinical perspective among fully COVID-19 vaccinated populations, compared to placebo (unvaccinated populations), published between 1 May 2021 and 30 September 2021. Eleven studies containing the data of 17.2 million participants were identified and included in our study. Pooled estimates of COVID-19 vaccines effectiveness (i.e., risk ratio, RR) against the DV with 95% confidence intervals were assessed using random-effect models. Publication bias was assessed using Egger's regression test and funnel plot to investigate potential sources of heterogeneity and identify any differences in study design. Results: A total population of 17.2 million (17,200,341 people) were screened for the COVID-19 vaccines' effectiveness against the DV. We found that 61.13% of the study population were fully vaccinated with two doses of COVID-19 vaccines. The weighted pooled incidence of COVID-19 infection was more than double (20.07%) among the unvaccinated population, compared to the fully vaccinated population (8.16%). Overall, the effectiveness of the COVID-19 vaccine against the DV was 85% (RR = 0.15, 95% CI: 0.07-0.31). The effectiveness of COVID-19 vaccines varied slidably by study designs, 87% (RR = 0.13, 95% CI: 0.06-0.30) and 84% (RR = 0.16, 95% CI: 0.02, 1.64) for cohort and case-control studies, respectively. Conclusions: The effectiveness of COVID-19 vaccines were noted to offer higher protection against the DV among populations who received two vaccine doses compared with the unvaccinated population. This finding would help efforts to maximise vaccine coverage (i.e., at least 60% to 70% of the population), with two doses among vulnerable populations, in order to have herd immunity to break the chain of transmission and gain greater overall population protection more rapidly.

RESUMO

BACKGROUND: Food insecurity and early sexual behaviors increase the risk of suicidal behavior, however their combined association on social behaviors receive little attention. Therefore, this study estimated the magnitude of adolescent global suicidal burden, it correlates with food insecurity and sexual behaviors, and assessed the combined association of food insecurity and sexual behaviors on the burden of suicidal behaviors (SBs) among school-going adolescent girls aged between 11 and 17 years. METHODS: The study design is multi-county, and pooled cross-sectional in nature. Data for 67 countries from the Global School-based Student Health Survey (GSHS) were used. A random-effects meta-analysis was used to generate national and overall pooled estimates of suicidal behaviors. Multinomial logistic regression analyses were employed to estimate the adjusted effect of independent factors and the combined associations of sexual behaviors and food insecurity on adolescent SBs in the context of global, regional, and country income groups and adjusted by a set of explanatory factors. RESULTS: The study included 121,248 girls aged 11-17 years. The population-weighted prevalence of high-level (SBs) was 40.65% among school-going girls who experienced sexual intercourse and 7.41% among those who reported severe food insecurity. However, the burden of SBs varied according to type of sexual behaviors and the age. The burden of SB among girls who had sexual intercourse with 1-2 sex partners, 3-4 sex partners, or >4 sex partners was 11.49%, 13.28%, or 18.43%, respectively. The high-level SB was double (23.08%) among adolescent girls who had first sexual intercourse aged 11-13 years old compared to adolescent girls aged 14-17 years (11.49%). The burden of SBs (for at least one SB, for two SBs, or for three SBs) were significantly associated with adolescent girls who experienced sexual intercourse (relative risk ratio, RRR = 2.04, 95% confidence interval, CI:1.83-2.28; RRR = 2.24, 1.99-2.52; RRR = 1.86, 1.59-2.18), sexual intercourse with four or more sex partners (RRR = 1.44, 1.15-1.79; RRR = 1.65, 1.33-2.06; RRR = 2.47, 1.94-3.16), first sexual intercourse aged 11-13 years (RRR = 1.22, 1.02-1.46; RRR = 1.51, 1.26-1.82; RRR = 2.26, 1.81-2.83), compared to adolescents who had no experience of SBs. Compared to adolescent girls who did neither experience food insecurity nor sexual intercourse, the overall burden of SBs (for at least one SB, for two SBs or for three SBs) were significantly higher among girls reporting to have experienced both food insecurity and sexual intercourse (RRR = 1.55, 1.29-1.86; RRR = 1.70, 1.42-2.04; RRR = 1.54, 1.26-1.88); and those reporting having experienced food insecurity but have never had sexual intercourse (RRR = 1.66, 1.48-1.87; RRR = 1.45, 1.26-1.67; RRR = 1.62, 1.36-1.92). However, it was significantly lower among girls reporting to have had sexual intercourse but never experienced food insecurity. This association was extended among adolescents in the context of regional and country income groups. CONCLUSION: The high burden of suicidal behaviors among adolescents calls for an urgent policy interventions to address food insecurity as a means to keep adolescents in school. The interventions should also aim to integrate safeguards that dissuade youngsters from early sex and protect them from sexual victimisation, and the associated adverse outcomes that that hamstring the attainment of SDG 3.4.2.

RESUMO

Slum dweller youth in Kampala, Uganda, face social economic exclusion and a plethora of health risks, and their needs are poorly understood. The aim of the current study was to analyze their needs and to suggest contextual evidence-based solutions to improve their well-being sustainably. We conducted a qualitative study involving 10 focus group discussions (FGDs; N = 113) and 20 key informant (KII) interviews. Emerging themes and sub-themes were identified, defined, reviewed, and organized and narrated following the structuration theoretical framework, which enabled the examination of the inherent capacity of slum dweller youth to make choices independently and the recurrent rules and resources that influence or limit the choices and opportunities available to them. The findings suggest that the slum dweller youth's ability to reach and fulfil their potential remains constrained by a confluence of individual and societal-level factors. The individual factors were poor quality of and dissatisfaction with life, and poor sexual and reproductive health practices. The societal-level factors were poor sexual and reproductive health services, and an extremely weak labor market. The needs of slum dweller youth in Kampala, Uganda, remain unaddressed, and leaving such a large population economically unproductive and dissatisfied with life is a recipe for political instability and insecurity. Interventions to address their needs need to adopt a whole-community approach in order to engage and empower all parts of the slum community and strengthen community structures that improve livelihoods and harness the opportunities that engender income fortification and socio-civic transformation for the youth.

RESUMO

Good sanitation and clean water are basic human rights yet they remain elusive to many rural communities in Sub-Saharan Africa (SSA). We carried out a cross sectional study to examine the impact of a four-year intervention aimed at improving access to water and sanitation and reducing waterborne disease, especially diarrhea in children under five years old. The study was carried out in April and May 2015 in Busangi, Chela and Ntobo wards of Kahama District of Tanzania. The interventions included education campaigns and improved water supply, and sanitation. The percentage of households (HHs) with access to water within 30 min increased from 19.2 to 48.9 and 17.6 to 27.3 in the wet and dry seasons, respectively. The percentage of HHs with hand washing facilities at the latrine increased from 0% to 13.2%. However, the incidence of diarrhea among children under five years increased over the intervention period, RR 2.91 95% CI 2.71-3.11, p < 0.0001. Availability of water alone may not influence the incidence of waterborne diseases. Factors such as water storage and usage, safe excreta disposal and other hygiene practices are critical for interventions negating the spread of water borne diseases. A model that articulates the extent to which these factors are helpful for such interventions should be explored.

RESUMO

BACKGROUND: While quality of life (QoL) has long been an explicit policy goal for international development programmes, no instruments have specifically been developed for measuring health-related QoL in resource-limited settings. The aim of this study was to develop and validate a QoL instrument for use in international aid and development programmes and to assess factors associated with QoL among youth participating in a civic engagement project in Kampala. DESIGN: Using systematic random sampling, data were collected on 663 participants aged between 13 and 24 years in Kampala. The QoL questionnaire included 36 questions divided into a two-part scale: 18 questions rated for satisfaction (Part 1) and 18 other questions rated on importance (Part 2). The total sample was randomly divided into two split-half samples: one for the exploratory factor analysis (EFA; N=310) and the other for the confirmatorty factor analysis (CFA; N=353). The effect of demographic, socio-economic, and lifestyle factors on QoL was assessed using linear regressions. RESULTS: The EFA yielded three factors: living conditions and lifestyle (seven items, α=0.84), social relationships (five items, α=0.86), and personal independence (five items, α=0.76). In the CFA, the initial model demonstrated a poor to marginal fit model. Its re-specification by examining modification indices resulted in a good model fit: Comparative Fit Index=0.95, Root Mean Square Error of Approximation=0.06, and p of Close Fit >0.05. The model incorporating perceived importance had lower Akaike Information Criteria and Bayesian Information Criteria values than the unweighted model, thereby providing very strong support to weight satisfaction scores with importance ratings when measuring QoL in Uganda. Poor QoL was associated with poor educational attainment, drug and substance misuse, and family disruption. CONCLUSIONS: The findings suggest that there is a relationship between QoL and lifestyle and structural issues among youth in Uganda. The study provides the first validated QoL measure to allow government and non-government organisations in low- and middle-income countries to track progress of international aid and development programmes.
