BMI for 女性 Age 45: Life Stage Context

Life Stage: Mature Adult (45–54)

At age 45, 女性 have a median BMI of 26 kg/m² based on CDC NHANES population data. The middle 50% of 女性 this age fall between 22.8 kg/m² (25th percentile) and 30 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 Mature Adult years (45–54) are often when lifestyle interventions have the greatest long-term impact on health outcomes.
