关键统计
BMI for 女性 Age 40: Life Stage Context
At age 40, 女性 have a median BMI of 25.6 kg/m² based on CDC NHANES population data. The middle 50% of 女性 this age fall between 22.5 kg/m² (25th percentile) and 29.6 kg/m² (75th percentile), a spread that indicates moderate variation in the population at this age.
BMI increases gradually with age, reflecting metabolic changes. Women experience hormonal shifts that affect body composition at key life stages. The Mid Adult years (35–44) are often when lifestyle interventions have the greatest long-term impact on health outcomes.
