ABSTRACT

Disasters can cause great physical and financial damage to pet owners in developing countries. These effects lead to severe psychological side effects on individuals and families. With the tendency of families to keep pets in these countries, many challenges have arisen regarding how to manage these pets before, during, and after disasters. Therefore, mitigation, prevention, and preparedness measures for these families should be prioritized in the disaster management cycle to minimize psychological effects such as posttraumatic stress disorder (PTSD) after losing pets.

ABSTRACT

Introduction: Routine immunization programs have focused on increasing vaccination coverage, which is equally important for decreasing vaccine-preventable diseases (VPDs), particularly in low- and lower-middle-income countries (LMICs). We estimated the trends and projections of age-appropriate vaccination coverage at the regional and national levels, as well as place of residence and wealth index in LMICs. Methods: In total, 174 nationally representative household surveys from 2000 to 2020 from 41 LMICs were included in this study. Bayesian hierarchical regression models were used to estimate trends and projections of age-appropriate vaccination. Results: The trend in coverage of age-appropriate Bacillus Calmette-Guérin (BCG), third dose of diphtheria, tetanus, and pertussis (DTP3), third dose of polio (polio3), and measles-containing vaccine (MCV) increased rapidly from 2000 to 2020 in LMICs. Findings indicate substantial increases at the regional and national levels, and by area of residence and socioeconomic status between 2000 and 2030. The largest rise was observed in East Africa, followed by South and Southeast Asia. However, out of the 41 countries, only 10 countries are estimated to achieve 90% coverage of the BCG vaccine by 2030, five of DTP3, three of polio3, and none of MCV. Additionally, by 2030, wider pro-urban and -rich inequalities are expected in several African countries. Conclusion: Significant progress in age-appropriate vaccination coverage has been made in LMICs from 2000 to 2020. Despite this, projections show many countries will not meet the 2030 coverage goals, with persistent urban-rural and socioeconomic disparities. Therefore, LMICs must prioritize underperforming areas and reduce inequalities through stronger health systems and increased community engagement to ensure high coverage and equitable vaccine access.

ABSTRACT

PURPOSE: There is limited information on preferences for place of care and death among patients with cancer in low- and middle-income countries (LMICs). The aim was to report the prevalence and determinants of preferences for end-of-life place of care and death among patients with cancer in LMICs and identify concordance between the preferred and actual place of death. METHODS: Systematic review and meta-analysis guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses was conducted. Four electronic databases were searched to identify studies of any design that reported on the preferred and actual place of care and death of patients with cancer in LMICs. A random-effects meta-analysis estimated pooled prevalences, with 95% CI, with subgroup analyses for region and risk of bias. RESULTS: Thirteen studies were included. Of 3,837 patients with cancer, 62% (95% CI, 49 to 75) preferred to die at home; however, the prevalence of actual home death was 37% (95% CI, 13 to 60). Subgroup analyses found that preferences for home as place of death varied from 55% (95% CI, 41 to 69) for Asia to 64% (95% CI, 57 to 71) for South America and 72% (95% CI, 48 to 97) for Africa. The concordance between the preferred and actual place of death was 48% (95% CI, 41 to 55) for South Africa and 92% (95% CI, 88 to 95) for Malaysia. Factors associated with an increased likelihood of preferred home death included performance status and patients with breast cancer. CONCLUSION: There is very little literature from LMICs on the preferences for end-of-life place of care and death among patients with cancer. Rigorous research is needed to help understand how preferences of patients with cancer change during their journey through cancer.

ABSTRACT

BACKGROUND: In low- and middle-income countries where vaccination rates are low, tetanus is still an important threat to public health. Although maternal and neonatal tetanus remains a major global health concern, its magnitude and determinates are not well studied. Therefore, this study aimed to assess the number of tetanus toxoid injections and associated factors among pregnant women in low- and middle-income countries. METHODS: Data from the most recent Demographic and Health Surveys, which covered 60 low- and middle-income countries from 2010 to 2022, was used for secondary data analysis. The study included a total of 118,704 pregnant women. A statistical software package, STATA 14, was used to analyze the data. A negative binomial regression of a cross-sectional study was carried out. Factors associated with the number of tetanus vaccinations were declared significant at a p-value of < 0.05. The incidence rate ratio and confidence interval were used to interpret the results. A model with the smallest Akaike Information Criterion and Bayesian Information Criterion values and the highest log likelihood was considered the best-fit model for this study. RESULTS: In low- and middle-income countries, 26.0% of pregnant women took at least two doses of the tetanus toxoid vaccine. Factors such as maternal education, primary (IRR = 1.22, 95% CI: 1.17, 1.26), secondary (IRR = 1.19, 95% CI: 1.15, 1.23), higher (IRR = 1.16, 95% CI: 1.12, 1.20), employment (IRR = 1.11, 95% CI: 1.09, 1.13), 1-3 ANC visits (IRR = 2.49, 95% CI: 2.41, 2.57), ≥4 visits (IRR = 2.94, 95% CI: 2.84, 3.03), wealth index (IRR = 1.06; 95% CI: 11.04, 1.08), ≥birth order (IRR = 1.04, 95% CI: 1.02, 1.27), distance to health facility (IRR = 1.02, 95% CI: 1.00, 1.03), and health insurance coverage (IRR = 1.08; 95% CI: 1.06, 1.10) had a significant association with the number of tetanus vaccinations among pregnant women. CONCLUSIONS AND RECOMMENDATIONS: This study concludes that the number of tetanus toxoid vaccinations among pregnant women in low- and middle-income countries is low. In the negative binomial model, the frequency of tetanus vaccinations has a significant association with maternal employment, educational status, wealth index, antenatal care visits, birth order, distance from a health facility, and health insurance. Therefore, the ministries of health in low and middle-income countries should give attention to those women who had no antenatal care visits and women from poor wealth quantiles while designing policies and strategies.

ABSTRACT

INTRODUCTION: Undernutrition poses a significant global public health challenge, adversely affecting childhood cognitive and physical development while increasing the risk of disease and mortality. Stunting, characterized by impaired growth and development in children due to insufficient psychological stimulation, frequent infections, and inadequate nutrition, remains a critical issue. Although economic growth alone cannot fully address the prevalence of stunting, there exists a robust correlation between a country's income level and childhood stunting rates. Countries with higher incomes tend to have lower rates of childhood stunting. Notably, while childhood stunting is declining worldwide, it remains persistent in Africa. Consequently, this study aims to assess the prevalence of childhood stunting and its determinants in low- and lower-middle-income African countries. METHOD: This study conducted a secondary analysis of standard demographic and health surveys in low- and lower-middle-income African countries spanning the period from 2010 to 2022. The analysis included a total sample of 204,214 weighted children under the age of five years. To identify the determinants of stunting, we employed a multilevel mixed-effect model, considering the three levels of variables. The measures of association (fixed effect) were determined using the adjusted odds ratio at a 95% confidence interval. Significance was declared when the association between the outcome variable and the explanatory variable had a p-value less than 0.05. RESULT: In low and lower-middle-income African countries, 31.28% of children under five years old experience stunting, with a 95% confidence interval ranging from 31.08% to 31.48%. The results from a multilevel mixed-effect analysis revealed that 24 months or more of age of child, male gender, low and high birth weight, low and high maternal BMI, no and low maternal education, low household wealth index, multiple (twin or triplet) births, rural residence, and low income of countries were significantly associated with childhood stunting. CONCLUSION: Stunting among children under five years of age in low- and lower-middle-income African countries was relatively high. Individual, community, and country-level factors were statistically associated with childhood stunting. Equally importantly, with child, maternal, and community factors of stunting, the income of countries needs to be considered in providing nutritional interventions to mitigate childhood stunting in Africa.

ABSTRACT

Background: The Global School Student Health Survey (GSHS) is being carried out by students in various countries across the globe to advance improved health programs for youth. However, in comparison to high-income countries, adolescents in low- and middle-income countries (LMICs) are generally at an early stage of understanding regarding physical activity (PA) and sedentary behavior (SB), often exhibiting low levels of PA and high levels of SB. Furthermore, there is limited evidence connecting PA and SB in school-going adolescents from LMICs. Purpose: The objective of this review was to synthesize the available evidence regarding PA and sedentary behavior among school-going adolescents in LMICs using data from the GSHS. Method: On March 18, 2023, a systematic literature search was performed across four electronic databases, namely Web of Science, PubMed, ScienceDirect, and EBSCO with n odaterestrictions. Studies were eligible if they: (1) utilization of data sourced from the Global Student-based Health Survey; (2) exploration of physical activity; (3) specific focus on adolescents; (4) conducted in low- and middle-income countries; (5) study design encompassing observational; (6) published as English journal articles. Results: Among the 29 studies included in the analysis, the majority revealed elevated levels of sedentary behavior and diminished levels of PA in low- and middle-income countries. Furthermore, notable disparities in physical engagement and sedentary behavior were noted between male and female adolescents (p < 0.001). Augmented PA among teenagers was observed to correlate with higher consumption of vegetables and fruits (AOR = 1.30; 95% CI [1.13-1.50]; p < 0.001), decreased alcohol consumption, and a reduced prevalence of loneliness and depression (aOR 1.37, 95% CI [1.18-1.59]). Conclusions: The results of this review affirm that in contrast to high-income countries, adolescents in low- and middle-income countries (LMICs) are in the early stages of comprehending physical activity, marked by low levels of PA. Physical activity and sedentary behavior in school-going adolescents from LMICs appear to be influenced by factors such as policies, cultural norms, socioeconomic conditions, as well as gender, and age.

ABSTRACT

The 'double burden of malnutrition' is a global health challenge that increasingly affects populations in both low- and middle-income countries (LMICs). This phenomenon refers to the coexistence of undernutrition and overweight or obesity, as well as other diet-related non-communicable diseases, in the same population, household or even individual. While noteworthy progress has been made in reducing undernutrition in some parts of the world, in many of these areas, the prevalence of overweight and obesity is increasing, particularly in urban areas, resulting in greater numbers of people who were undernourished in childhood and have overweight or obesity in adulthood. This creates a complex and challenging situation for research experts and policymakers who must simultaneously address the public health burdens of undernutrition and overweight/obesity. This review identifies key challenges and limitations in the current research on the double burden of malnutrition in individuals, including the need for a more comprehensive and nuanced understanding of the drivers of malnutrition, the importance of context-specific interventions and the need for greater attention to the food environment and food systems. We advocate for the re-evaluation of research strategies and focus, with a greater emphasis on multidisciplinary and systems approaches and greater attention to the synergistic relationship between the biological, environmental, commercial and socio-economic determinants of malnutrition. Addressing these key challenges can enable us to better comprehend and tackle the multifaceted and dynamic issues of the double burden of malnutrition, particularly in individuals and work towards more effective and sustainable solutions.

ABSTRACT

OBJECTIVE: To measure the proportion of women's preferences for CS in hospitals with high caesarean section rates and to identify related factors. DESIGN: A cross-sectional hospital-based postpartum survey was conducted. We used multilevel multivariate logistic regression and probit models to analyse the association between women's caesarean section preferences and maternal characteristics. Probit models take into account selection bias while excluding women who had no preference. SETTING: Thirty-two hospitals in Argentina, Thailand, Vietnam and Burkina Faso were selected. PARTICIPANTS: A total of 1,979 post-partum women with no potential medical need for caesarean section were included among a representative sample of women who delivered at each of the participating facilities during the data collection period. FINDINGS: The overall caesarean section rate was 23.3 %. Among women who declared a preference in late pregnancy, 9 % preferred caesarean section, ranging from 1.8 % in Burkina Faso to 17.8 % in Thailand. Primiparous women were more likely to prefer a caesarean section than multiparous women (ß=+0.16 [+0.01; +0.31]; p = 0.04). Among women who preferred caesarean section, doctors were frequently cited as the main influencers, and "avoid pain in labour" was the most common perceived benefit of caesarean section. KEY CONCLUSIONS: Our results suggest that a high proportion of women prefer vaginal birth and highlight that the preference for caesarean section is linked to women's fear of pain and the influence of doctors. These results can inform the development of interventions aimed at supporting women and their preferences, providing them with evidence-based information and changing doctors' behaviour in order to reduce the number of unnecessary caesarean sections. CLINICAL TRIAL REGISTRY: The QUALI-DEC trial is registered on the Current Controlled Trials website (https://www.isrctn.com/) under the number ISRCTN67214403.

ABSTRACT

BACKGROUND AND AIMS: This review aims to estimate the prevalence of undernutrition among migrants, refugees, internally displaced children, and children of migrated parents living in lower-middle-income countries. METHODS: PubMed, Scopus, Science-Direct, CINAHL-Plus, & Google Scholar were searched for peer-reviewed evidence published between January 2010 to March 2023. Two researchers independently examined the studies and retrieved the data. The internal and external validity of the studies was assessed using the NIH quality assessment tool, and a checklist adapted from Downs & Black, Bracht & Glass, and Del Siegle's guidelines. A random effect model was chosen to pool the estimates. Subgroup analysis, Meta-regression, and sensitivity analysis were done to explore the source of heterogeneity and the robustness of estimates. RESULTS: Among the 1978 records initially searched, 21 studies were selected for analysis. The pooled prevalence estimates for stunting, wasting, and underweight were estimated to be 29.39% (Confidence Interval [CI] 21.69-37.73; I2 99%; p < 0.01), 12.76% (CI 7.84-18.68; I2 99%; P < 0.01), and 24.05% (CI 16.17-32.94; I2 100%; p < 0.001) respectively. Among different WHO regions, all three undernutrition estimates were higher in LMICs belonging to the Southeast Asian region (Stunting 37.62%; wasting 14.28% and underweight 31.24%). Undernutrition among migrant Indian children was 43.55%, 18.71%, and 37.45% respectively. High heterogeneity was noted across all estimates with I2-value >90%. Sensitivity analysis across indicators showed the stability of our estimates. CONCLUSIONS: The extent of undernutrition, particularly wasting was high among migrant/refugee children living in lower-middle-income countries. Measures should be taken to strengthen the government-subsidized public food distribution system, increase healthcare outreach, and ensure public health insurance coverage among the migrant population.

ABSTRACT

OBJECTIVE: Electrical burn injuries (EBIs) represent an important subset of burn injuries, but the information on them from the global level is limited. We aimed to investigate the characteristics and risk factors for EBIs reported to the World Health Organization Global Burn Registry. METHODS: Patients with EBIs and non-EBIs were identified from the registry. Patient demographics, income of the country, setting of the injury occurred, and outcomes were described and compared. Multivariable analysis was performed to identify risk factors associated with the EBIs and their outcomes. RESULTS: Of the 9276 patients, 814 (8.8%) were grouped as EBIs. EBIs patients had a median age of 28 years, and they were predominantly males (89.2%). EBIs were more likely to occur in lower-middle- and low-income countries (60.9% versus 43.4%) and in an occupational setting (49.1% versus 6.7%) than the non-EBIs. Older age, male, lower-income, and occupational and public setting were risk factors for EBIs. For EBIs patients, adolescents and young adults, those from low-middle and low-income countries, and those injured by high-voltage electricity were more likely to have more than 15% of the total body surface area. In addition, those from low-middle and low-income countries and those injured by high-voltage electricity were more likely to die. CONCLUSION: The characteristics of EBIs are significantly different from that of non-EBIs. To prevent EBIs and avoid unpleasant outcomes, particular attention should be given to adolescent boys and young adult men who are employed in electrical jobs in lower-income countries.

ABSTRACT

OBJECTIVES: Studies suggest that living at high altitude decreases obesity risk, but this research is limited to single-country analyses. We examine the relationship between altitude and body mass index (BMI) among women living in a diverse sample of low- and middle-income countries. MATERIALS AND METHODS: Using Demographic and Health Survey data from 1 583 456 reproductive age women (20-49 years) in 54 countries, we fit regression models predicting BMI and obesity by altitude controlling for a range of demographic factors-age, parity, breastfeeding status, wealth, and education. RESULTS: A mixed-effects model with country-level random intercepts and slopes predicts an overall -0.162 kg/m2 (95% CI -0.220, -0.104) reduction in BMI and lower odds of obesity (OR 0.90, 95% CI 0.87, 0.95) for every 200 m increase in altitude. However, countries vary dramatically in whether they exhibit a negative or positive association between altitude and BMI (34 countries negative, 20 positive). Mixed findings also arise when examining odds of obesity. DISCUSSION: We show that past findings of declining obesity risk with altitude are not universal. Increasing altitude predicts slightly lower BMIs at the global level, but the relationship within individual countries varies in both strength and direction.

ABSTRACT

INTRODUCTION: As the largest profession within the healthcare industry, nursing and midwifery workforce (NMW) provides comprehensive healthcare to children and their families. This study quantified the independent role of NMW in reducing under-5 mortality rate (U5MR) worldwide. DESIGN: A retrospective, observational and correlational study to examine the independent role of NMW in protecting against U5MR. METHODS: Within 266 "countries", the cross-sectional correlations between NMW and U5MR were examined with scatter plots, Pearson's r, nonparametric, partial correlation and multiple regression. The affluence, education and urban advantages were considered as the potential competing factors for the NMW-U5MR relationship. The NMW-U5MR correlations in both developing and developed countries were explored and compared. RESULTS: Bivariate correlations revealed that NMW negatively and significantly correlated to U5MR worldwide. When the contributing effects of economic affluence, urbanization and education were removed, the independent NMW role in reducing U5MR remained significant. NMW independently explained 9.36% U5MR variance. Multilinear regression selected NMW as a significant factor contributing an extra 3% of explanation to U5MR variance when NMW, affluence, education and urban advantage were incorporated as the predicting variables. NMW correlated with U5MR significantly more strongly in developing countries than in developed countries. CONCLUSION: NMW, indexing nursing and midwifery service, was a significant factor for reducing U5MR worldwide. This beneficial effect explained 9.36% of U5MR variance which was independent of economic affluence, urbanization and education. The NMW may be a more significant risk factor for protecting children from dying under 5 years old in developing countries. As a strategic response to the advocacy of the United Nations to reduce child mortality, it is worthy for health authorities to consider a further extension of nurses and midwives' practice scope to enable communities to have more access to NMW healthcare services.

ABSTRACT

Globally, 149 million children under 5 years of age are estimated to be stunted (length more than 2 standard deviations below international growth standards)1,2. Stunting, a form of linear growth faltering, increases the risk of illness, impaired cognitive development and mortality. Global stunting estimates rely on cross-sectional surveys, which cannot provide direct information about the timing of onset or persistence of growth faltering-a key consideration for defining critical windows to deliver preventive interventions. Here we completed a pooled analysis of longitudinal studies in low- and middle-income countries (n = 32 cohorts, 52,640 children, ages 0-24 months), allowing us to identify the typical age of onset of linear growth faltering and to investigate recurrent faltering in early life. The highest incidence of stunting onset occurred from birth to the age of 3 months, with substantially higher stunting at birth in South Asia. From 0 to 15 months, stunting reversal was rare; children who reversed their stunting status frequently relapsed, and relapse rates were substantially higher among children born stunted. Early onset and low reversal rates suggest that improving children's linear growth will require life course interventions for women of childbearing age and a greater emphasis on interventions for children under 6 months of age.

ABSTRACT

Growth faltering in children (low length for age or low weight for length) during the first 1,000 days of life (from conception to 2 years of age) influences short-term and long-term health and survival1,2. Interventions such as nutritional supplementation during pregnancy and the postnatal period could help prevent growth faltering, but programmatic action has been insufficient to eliminate the high burden of stunting and wasting in low- and middle-income countries. Identification of age windows and population subgroups on which to focus will benefit future preventive efforts. Here we use a population intervention effects analysis of 33 longitudinal cohorts (83,671 children, 662,763 measurements) and 30 separate exposures to show that improving maternal anthropometry and child condition at birth accounted for population increases in length-for-age z-scores of up to 0.40 and weight-for-length z-scores of up to 0.15 by 24 months of age. Boys had consistently higher risk of all forms of growth faltering than girls. Early postnatal growth faltering predisposed children to subsequent and persistent growth faltering. Children with multiple growth deficits exhibited higher mortality rates from birth to 2 years of age than children without growth deficits (hazard ratios 1.9 to 8.7). The importance of prenatal causes and severe consequences for children who experienced early growth faltering support a focus on pre-conception and pregnancy as a key opportunity for new preventive interventions.

ABSTRACT

Importance: Aspirin is an effective and low-cost option for reducing atherosclerotic cardiovascular disease (CVD) events and improving mortality rates among individuals with established CVD. To guide efforts to mitigate the global CVD burden, there is a need to understand current levels of aspirin use for secondary prevention of CVD. Objective: To report and evaluate aspirin use for secondary prevention of CVD across low-, middle-, and high-income countries. Design, Setting, and Participants: Cross-sectional analysis using pooled, individual participant data from nationally representative health surveys conducted between 2013 and 2020 in 51 low-, middle-, and high-income countries. Included surveys contained data on self-reported history of CVD and aspirin use. The sample of participants included nonpregnant adults aged 40 to 69 years. Exposures: Countries' per capita income levels and world region; individuals' socioeconomic demographics. Main Outcomes and Measures: Self-reported use of aspirin for secondary prevention of CVD. Results: The overall pooled sample included 124 505 individuals. The median age was 52 (IQR, 45-59) years, and 50.5% (95% CI, 49.9%-51.1%) were women. A total of 10 589 individuals had a self-reported history of CVD (8.1% [95% CI, 7.6%-8.6%]). Among individuals with a history of CVD, aspirin use for secondary prevention in the overall pooled sample was 40.3% (95% CI, 37.6%-43.0%). By income group, estimates were 16.6% (95% CI, 12.4%-21.9%) in low-income countries, 24.5% (95% CI, 20.8%-28.6%) in lower-middle-income countries, 51.1% (95% CI, 48.2%-54.0%) in upper-middle-income countries, and 65.0% (95% CI, 59.1%-70.4%) in high-income countries. Conclusion and Relevance: Worldwide, aspirin is underused in secondary prevention, particularly in low-income countries. National health policies and health systems must develop, implement, and evaluate strategies to promote aspirin therapy.

ABSTRACT

BACKGROUND: Full birth histories (FBHs) are a key tool for estimating fertility and child mortality in low- and middle-income countries, but they are lengthy to collect. This is not desirable, especially for rapid turnaround surveys that ought to be short (e.g., mobile phone surveys). To reduce the length of the interview, some surveys resort to truncated birth histories (TBHs), where questions are asked only on recent births. METHODS: We used 32 Malaria Indicator Surveys that included TBHs from 18 countries in sub-Saharan Africa. Each set of TBHs was paired and compared to an overlapping set of FBHs (typically from a standard Demographic and Health Survey). We conducted a variety of data checks, including a comparison of the proportion of children reported in the reference period and a comparison of the fertility and mortality estimates. RESULTS: Fertility and mortality estimates from TBHs are lower than those based on FBHs. These differences are driven by the omission of events and the displacement of births backward and out of the reference period. CONCLUSIONS: TBHs are prone to misreporting errors that will bias both fertility and mortality estimates. While we find a few significant associations between outcomes measured and interviewer's characteristics, data quality markers correlate more consistently with respondent attributes, suggesting that truncation creates confusion among mothers being interviewed. Rigorous data quality checks should be put in place when collecting data through this instrument in future surveys.
