Micronutrient status among women in the midlife in selected Asian regions: a scoping review.

Abstract

Micronutrient status is critical for the health and well-being of midlife women during the menopausal transition. However, data on micronutrient intake and status among midlife Asian women remain limited. This review examined the landscape of micronutrient intake, deficiency, and health impact in this population. Using a scoping review approach guided by a Population-Concept-Contextframework, we descriptively synthesized evidence from population-level and peer-reviewed data across six Asian regions (India, Indonesia, Japan, the Philippines, South Korea, and Taiwan). The review focuses on B-vitamins, calcium, vitamin D, and magnesium, due to their roles in metabolic, musculoskeletal, cognitive, and mental health. Eighty-six publications and ten reports were identified. Despite methodological differences, evidence consistently indicated suboptimal intakes or deficiency. Available data suggested associations between adequate intake or status and better bone health, metabolism, cognition, and quality of life. Micronutrient inadequacy among this population is common yet under-recognized. Strengthening surveillance and developing targeted interventions are critical to support healthy aging and disease prevention among women in midlife and beyond.
