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…
Spatiotemporal association patterns in a supergroup of Rwenzori black‐and‐white colobus ( Colobus angolensis ruwenzorii ) are consistent with a multilevel society
Primates display broad diversity in their social organization. The social groups of a few primate species are organized in a multilevel fashion, with large groups composed of multiple, core one‐male units (OMUs). A characteristic of multilevel societies is that the higher levels can include hundreds of individuals. The Rwenzori black‐and‐white colobus ( Colobus angolensis ruwenzorii ) in the montane forests of Rwanda form supergroups and have bee…

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…
Infant handling by female mountain gorillas: Establishing its frequency, function, and (ir)relevance for life history evolution
OBJECTIVES: Infant handling describes cases in which youngsters are temporarily removed from the care of their mothers and "taken care of" (held, carried, etc.) by other conspecifics. Handlers may gain indirect fitness benefits from these actions and can practice mothering skills, thereby improving the odds of survival of their own infants. Great apes are notable for displaying little infant handling. Apart from anecdotal observations, no publish…
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…
Household agricultural activities and child growth: Evidence from rural Timor-Leste
Childhood under-nutrition and malnutrition are prevalent in low and middle-income countries. Where agriculture is the primary source of food production, consumption, and cash income, it has a close relationship with health and nutrition in these emerging economies. Although Timor-Leste achieved lower middle-income status in 2011, national economic growth has not delivered anticipated nutritional dividends. Seeking to redress a lack of research th…
The varied path to adulthood: Plasticity in developmental timing in hylobatids
Maturation includes physical, reproductive, and social aspects that develop asynchronously. Intra- and inter-individual variation in the relative timing of each aspect reflects context-dependent plasticity. Plasticity in developmental timing may be important for the family-living small apes (family Hylobatidae), where reproductive opportunities are monopolized by territorial breeding pairs. Data on development in hylobatids are so far limited due…
Kloss gibbon ( Hylobates klossii ) behavior facilitates the avoidance of human predation in the Peleonan forest, Siberut Island, Indonesia
Kloss gibbons (Hylobates klossii) are endemic to the Mentawai Islands in Indonesia and have been subject to human predation for more than 2000 years in the absence of any other significant predators. We investigate the behavior of Kloss gibbons that may be attributed to avoiding human predation. We observed Kloss gibbons in the Peleonan forest in the north of Siberut Island, the northernmost of the Mentawai island chain, over 18 months in 2007 an…

Child size and household characteristics in rural Timor‐Leste
OBJECTIVES: The main objective was to determine those characteristics of the family and household that affects child health (as measured by child size for age) in the rural Ossu area of Timor-Leste. METHODS: Interviews of parents in 102 households assessed reproductive histories, the amount and type of resources available and family composition (number, sex, and age of members). Height, weight, and mid-upper arm circumference were measured for al…

Life Span Extension in Humans Is Self-Reinforcing: A General Theory of Longevity
This article proposes that longevity is not merely the result of an absence of mortality but a self-reinforcing and positively selected life-history trait in social species. It argues that a small increase in longevity is amplified as (1) reductions in mortality at young ages increase natural selection for mechanisms of maintenance and repair at all older ages as well as increasing the potential for intergenerational transfers; (2) intergenera-ti…
