This research investigated the effect of marital transition on body weight changes among Indonesian adults aged 20 year old or older. It hypothesized that transition from unmarried to married adults significantly increased the body weight. We analyzed 26,386 adults from Indonesian Family Life Survey waves 4 and 5 using multiple linear regression with wide form of longitudinal data. The analysis was modelled based on sex (male and female) and generation (younger and older). The analysis controlled for sociodemographic, health behaviors, and psychological aspect. The results revealed that compared to those remain never married, transition from never married to be married significantly increased 2.30 Kilograms (kg) body weight for the whole sample as well as for sub-groups analysis. The transition from separated/widowed/divorced to married also significantly increased body weight in the whole sample and sub-group analysis, except male. In contrast, the transition from married to separated/divorced/widowed decreased body weight among the whole sample, males, and younger. The body weight was found decreased 1.31 kg among males and younger generation who remained married decreased, among males, older, and younger generations who remained divorced/separated, and among the whole sample and younger generations who remained widowed. Findings align with the life course theory and existing researches indicating that lifestyle changes following marriage, including eating habits and reduced physical activity, may contribute to weight gain. Health interventions targeting newlyweds, encouraging healthy behaviors such as maintaining physical activity and making nutritious dietary choices early in marriage are needed.
本研究调查了婚姻转变对20岁及以上印度尼西亚成年人体重变化的影响。研究假设从未婚到已婚成年人的转变会显著增加体重。我们使用具有广泛形式纵向数据的多元线性回归分析了来自印度尼西亚家庭生活调查第4波和第5波的26386名成年人。该分析基于性别（男性和女性）和代际（年轻和年长）进行建模。分析控制了社会人口统计学、健康行为和心理方面。结果显示，与那些从未结婚的人相比，从未婚到已婚的转变在整个样本以及亚组分析中显著增加了2.30千克的体重。从分居/丧偶/离婚到已婚的转变在整个样本和亚组分析中也显著增加了体重，但男性除外。相比之下，从已婚到分居/离婚/丧偶的转变在整个样本、男性和年轻人中导致体重下降。在已婚的男性和年轻一代、离婚/分居的男性、年长和年轻一代以及丧偶的整个样本和年轻一代中，体重下降了1.31千克。研究结果与生命历程理论和现有研究一致，表明婚后生活方式的改变，包括饮食习惯和体育活动的减少，可能导致体重增加。需要针对新婚夫妇的健康干预措施，鼓励他们在婚后早期保持体育活动和做出营养饮食选择等健康行为。
