Women’s Life Trajectories in Rural Timor-Leste: A Life History and Life Course Perspective on Reproduction and Empowerment
Women’s reproductive decisions and life trajectories are shaped by an interplay of biological, social, and ecological factors. While Life History Theory (LHT) has traditionally been applied in biological sciences to examine reproductive trade-offs, its integration with Life Course Theory (LCT) and empowerment frameworks offers a novel approach to understanding how structural and environmental conditions shape women’s reproductive behaviours and h…
Worldwide trends in underweight and obesity from 1990 to 2022: A pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
BACKGROUND: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…
The seasonal relationships between household dietary diversity and child growth in a rural Timor‐Leste community
Both child growth and dietary diversity are poor in rural Timor-Leste. The rainy season is associated with food scarcity, yet the association between seasonal scarcity, food diversity, and child growth is underdocumented. This study assesses the relationship between household dietary diversity and children's standardized growth across the 2018 food-scarce (April-May; post-rainy period) and post-harvest (October) seasons in the agricultural commun…
Relationships of Resource Strategies, Family Composition, and Child Growth in Two Rural Timor-Leste Communities
Subsistence and economic activities undertaken by households in the context of transition from subsistence farming to cash economies are sometimes seen as substitutable with only minimal reference to the households themselves. We use data from in-depth interviews of 190 householders in Ossu (mountains) and Natarbora (coastal plains), Timor-Leste, to query relationships of family composition, resource strategies, and their relationships to childre…
Determinants of objectively measured physical activity in rural East Timorese children
OBJECTIVES: The human juvenile period evolved as a period of learning and physical development in a family environment that subsidizes the costs of these processes. Children allocate energy to physical activity, maintenance, and growth. How energy is allocated has consequences for adult body size and other life-history traits. In subsistence agriculture populations, where child contributions to the household economy are common and energy availabi…
Growth curves and the international standard: How children's growth reflects challenging conditions in rural Timor‐Leste
OBJECTIVES: Population-specific growth references are important in understanding local growth variation, especially in developing countries where child growth is poor and the need for effective health interventions is high. In this article, we use mixed longitudinal data to calculate the first growth curves for rural East Timorese children to identify where, during development, deviation from the international standards occurs. MATERIALS AND METH…
Rural Livelihood Variation and its Effects on Child Growth in Timor-Leste
Household resources and seasonal patterns of child growth in rural Timor‐Leste
OBJECTIVES: This study aimed to determine through detailed contextual investigation the effects of seasonal resource shortages, and household and individual level differences, on child growth in rural Timor-Leste. We compared trends in growth across two rural Timorese villages with different ecologies. METHODS: Heads of 104 households in Natarbora, Timor-Leste, were interviewed and resource levels assessed during the food shortage season. In thes…
