18岁女性的完整BMI数据。
关键统计
BMI for 女性 Age 18: Life Stage Context
At age 18, 女性 have a median BMI of 21.5 kg/m² based on CDC NHANES population data. The middle 50% of 女性 this age fall between 19 kg/m² (25th percentile) and 25.5 kg/m² (75th percentile), a spread that indicates significant variation across individuals at this age group.
BMI increases gradually with age, reflecting metabolic changes. Women experience hormonal shifts that affect body composition at key life stages. Establishing healthy BMI patterns during the Young Adult years sets a strong foundation for long-term health.
