Menarche and pubertal onset vary across populations but understanding age-at-menarche (AAM) and pubertal growth tempo is limited in low-income settings. Identifying factors influencing pubertal development is vital for creating targeted health and education programmes supporting adolescent girls' well-being. Baseline data (n = 1045) from the Ten2Twenty-Ghana study were analysed to examine menarche attainment, pubertal development, AAM, and the associated factors among girls aged 10-17 years in the Mion district, Ghana. The data collection methods included anthropometry, body composition, haemoglobin status, a qualitative 24-hour dietary recall, a food frequency questionnaire, and a pubertal development score (PDS). Binary logistic and linear regression analyses were used to model odds ratios for menarche attainment and regression coefficients for AAM and PDS. About 19.9% of the girls had experienced menarche, with a mean AAM of 13.4 ± 1.5 years. Among post-menarche girls (n = 205/1045), 12.2% and 15.1% experienced early (AAM < 12 years) and late menarche (AAM < 15 years), respectively. The mean PDS was 1.8 ± 0.7 out of 4. Among the adolescent girls, 36.2% were prepubertal, 17.0% early -pubertal, 18.6% mid-pubertal, 27.9% late pubertal, and less than 1% were in the post-pubertal stage. An increase in fat mass (FM), fat-free mass (FFM), height-for-age-z-score (HAZ), and body mass index-for-age-z-score (BAZ) was observed with puberty progression, but a steep decline in HAZ was noticed for girls in late puberty, increasing again post-puberty. Being older (adjusted odds ratio (AOR) = 2.06, 95% C.I.: 1.83, 2.31), stunted (AOR= 0.20, 95% C.I.: 0.10, 0.40), thin (AOR = 0.30, 95% C.I.: 0.11, 0.80), and overweight/obese (AOR = 7.29, 95% C.I.: 2.60, 20.43) were the significant predictors of menarche attainment. Being older (β = 0.39, P < 0.0001), stunted (β= -0.92, P = 0.01), thin (β = 1.25, P = 0.01), and having a literate mother (β = -0.72, P = 0.03) were significantly associated with AMM. A higher HAZ, FM, FFM, age, and Konkomba ethnicity were positively associated with higher PDS. This study highlights the complexity of factors influencing menarche and pubertal development. These insights are essential for developing targeted health and educational programmes that address nutritional and socio-demographic disparities to promote adolescent girls' well-being and healthy pubertal development.

Menstrual hygiene management (MHM) is an important but often neglected aspect of women's health worldwide, especially in developing and disaster-prone countries, such as Bangladesh. This qualitative study aimed to investigate awareness, attitudes, and practices related to MHM among girls in the Haor region, particularly during floods. The study adopts a phenomenological approach, and data were collected using purposive sampling from 33 women aged 15 years and above who resided in the Haor region. Thematic analysis was employed to identify the patterns, themes, and subthemes within the qualitative data. The study reveals a significant lack of widespread knowledge about menstruation among girls in the Haor area, which is associated with unfavourable family and social attitudes, and stigma or taboos. Natural hazards, cultural barriers, access to the market, economic incapacity, and inadequate infrastructure make it very difficult to manage menstruation, which is especially aggravated during floods due to displacement and shelter on the roadside, primary schools, and other people's houses. This research emphasises the need for tailored MHM programmes from the government to address the unique challenges faced by women in Haor regions. Provision of sanitary napkins and essential medicines, maintaining stock in shelters, and equipping community clinics with MHM-related healthcare services are essential. Finally, NGOs should prioritise MH within their scope of work.

Household air pollution (HAP) presents numerous health challenges. The association between HAP and sleep problems has not been extensively studied. This paper examined the effect of HAP due to solid fuel use on sleep problems among older adults in India. Data from the initial phase of the Longitudinal Aging Study in India, which included 51,060 individuals aged 50 years and older, was utilised. Sleep problems were defined as experiencing difficulty falling asleep, waking up during the night, or waking up too early at least five times per week and were classified as a binary variable. Exposure to HAP was defined as the use of solid fuel for household purposes. Multivariate logistic regression was employed to assess the association, and additionally, interaction analysis was conducted to explore the potential moderating effects of age, gender, and residence on this association. The prevalence of sleep problems among older adults was around 12.7%. Sleep problems were higher among older adults who used solid fuel for cooking (OR = 1.25; 95% CI: 1.17, 1.33) and other purposes (OR = 1.13; 95% CI: 1.06, 1.20) in the adjusted model. The place of cooking, ventilation, and type of stove played a significant role in the association between solid fuel use and sleep problems. Individuals over 65, females, and those residing in rural areas were particularly vulnerable to sleep problems due to HAP exposure. The findings highlight the importance of reducing HAP exposure by transitioning to clean fuels as a public health priority within initiatives aimed at promoting healthy aging.

The UK has experienced alarming increases in the number of individuals living with food insecurity as a result of the rise in the cost of living. The mechanisms linking household economic insecurity to food insecurity, and perceived health outcomes, are not well understood. The aim of this study was to explore how individuals with lived experience of food insecurity are coping with the rise in the cost of living, the trade-offs they might be making between food and other household expenses, and how these might impact eating behaviours and health outcomes. Using a qualitative inductive approach rooted in hermeneutic phenomenology, nine semi-structured interviews were conducted among individuals using charity-run food provision services in Bristol, UK. Narrative accounts from these interviews were analysed thematically. Almost all participants were recipients of benefits at the time of interviews and were living under high levels of economic insecurity. The rise in the cost of living forced complex budget management strategies, including relying on donated food and shoplifting. It also influenced eating behaviours through altered cooking strategies to save energy, substituting food for cheaper, less-nutritious, alternatives, and rationing meals. Food insecurity was experienced as a form of psychosocial violence, engendering high levels of stress, particularly for individuals with diet-related chronic diseases. There is therefore an urgent need for policies that tackle structural causes of overall household economic insecurity, and improve economic access to adequate nutritious foods, to prevent further entrenching social inequalities.

As COVID-19 spread rapidly during the early months of the pandemic, many communities around the globe anxiously waited for a vaccine. At the start of the pandemic, it was widely believed that Africa would be a significant source of infection, and thus, vaccinating African communities became a primary goal among local and global health authorities. However, when the COVID-19 vaccine became available in March 2021 in Sierra Leone, many people viewed it with scepticism and hesitation. While much literature has focused on access and distribution-related challenges for vaccination in the region, a growing number of studies discuss vaccine hesitancy as driving low vaccine uptake. Shifting attention to understanding the determinants of vaccine hesitancy remains fundamental to increasing vaccination rates, as negative vaccine perceptions tend to delay or prevent vaccination. This study sought to do this by assessing, through semi-structured qualitative interviews, vaccine-related attitudes and experiences of residents of Sierra Leone's Kono District. In contrast to studies that utilise "knowledge-deficit" models of belief, however, this study drew upon the vaccine anxieties framework (Leach and Fairhead, 2007), which views vaccines as being imbued with personal, historical, and political meaning. Findings suggest that important bodily, social, and political factors, including fear of side effects, the spread of misinformation prompted by poor messaging strategies, and distrust of government and international actors, influenced people's COVID-19 vaccine attitudes and behaviours. It is hoped that the study's findings will inform future policies and interventions related to vaccine uptake in Africa and globally.

This study aimed to investigate the influence of socio-demographic and epidemiological factors on the secular changes in body size indicators (height, weight, and BMI) among young adults aged 17-22 years in Moscow from the early 20th century to the present. Published average anthropometric data from screening surveys conducted from 1880/1925-26 to 2020-21 were analysed (4,823 males and 5,952 females), along with demographic data from the Federal State Statistics Service of the Russian Federation. Findings revealed consistent anthropometric trends and strong associations between secular changes in body size of Moscow youth and socio-demographic indicators such as population size, life expectancy, and infant mortality rates. An increase in height and weight was noted against the backdrop of urbanisation, increased life expectancy, and reduced infant mortality. These results indicate that the urbanisation process and the transformation of the epidemiological landscape in 20th-century Russia - marked by enhancements in public health, modernisation of the healthcare system, and medical advancements - have had a significant impact on changes in body size across generations. Notably, from the mid-20th century onwards, with the exception of the final decade, conditions favourable to growth and development were established, culminating in a significant increase in definitive anthropometric parameters across successive generations. The findings underscore the imperative for policymakers to bolster investments in urban development, healthcare, and education. Such strategic investments are essential for sustaining and amplifying the positive physical development trends witnessed.

Air pollution in households is a prime contributor to health issues in developing countries, as in the case of India. According to the latest National Family Health Survey Report 2022, more than half of India's rural population and 41 per cent overall still depend on solid or unclean fuel combustions, which may reflect in future health hazards. Thus, it is crucial to understand the issue empirically. To that end, the study traces the transitional pattern of unclean cooking fuel users towards clean fuel over the last 30 years using responses from all five National Family Health Survey rounds. Further, the study uses an adjusted probit model to analyse the determinants that lead to the choice of cooking fuel in a household and a logistic model to examine the association between the choice made and the respiratory health of children under five. The empirical results show that the number of households using unclean fuel has declined over the years, with a slightly higher decline in the last five years. Moreover, it also shows that poverty status and place of residence significantly influence cooking fuel choice. Additionally, children residing in households that use clean fuels are less likely to suffer respiratory infections. In conclusion, the present study provides strong evidence to ameliorate the existing policies in a way that exhorts clean energy use. The authors propose pro-poor, pro-rural policies to expedite the clean energy transition, benefitting the most vulnerable households.

High premature adult deaths in developing countries are gaining attention, as recent studies show their increasing impact on overall mortality rates. This paper has twofold objectives: firstly, it investigates the long-term trends and patterns of adult mortality between 1970 and 2018 in India. Secondly, it attempts to detect age, period, and cohort (APC) effects on adult mortality decline over time. Data on age-specific mortality rates and disease-adjusted life years for adult age groups (15-59 years) were collected from the Sample Registration System and the Global Burden of Disease study, respectively. The trends in age-standardized mortality rates were presented graphically, and critical change points were highlighted using a change-point analysis. The intrinsic estimator model was applied to estimate the independent effects of APC on adult mortality. The findings revealed that adult mortality declined between 1970 and 2018 with multiple critical change points. The APC effects showed a notable decline in adult mortality during 2005-2018 and for the recent birth cohorts, 1980-2004. However, the rate of mortality declined slowly over time. Results also indicated that mortality started increasing from mid-adult ages and peaked in older adult ages due to the age effects and provided evidence of a rise in adult life loss due to non-communicable diseases in recent years. Overall, the study underscores the importance of implementing health policies aimed at reducing life loss in the most economically active ages that can have long-term negative implications for the country's economic growth.

During the pandemic period, the use of health services by disadvantaged groups such as immigrants has deteriorated. The study aims to evaluate the use of antenatal care services by Syrian pregnant women during the pandemic. It is a cross-sectional type of study. The population consisted of 495 pregnant women who applied to the Extended Migrant Health Center (EMHC) between August 2020 and December 2022. Demographic data and pregnancy-related health records were examined through the system records, without any contact with the pregnant women. The percentage of pregnant women who had timely follow-up for each antenatal visit were 11.5% (n=56), 17.2% (n=80), 20.0% (n=88), and 17.4% (n=73), respectively. Only 17.7% (n=87) of the pregnant women made the recommended number of visits during their pregnancy period. The recommended number of follow-ups was statistically significantly higher in women with high-risk pregnancies (p=0.045). Of the pregnant women, 27.4% had anaemia and 2.4% had hypertension. The use of antenatal care in immigrant pregnant women is very low. Interventions are needed in this regard. Increasing the utilization of antenatal care services by immigrant pregnant women is extremely important for both the health of the pregnant woman and the health of the baby.
