Physical activity patterns in healthy middle-aged women

Area of Science:

• Gerontology
• Public Health
• Exercise Science

Background:

• Physical activity (PA) assessment in women nearing menopause often overlooks non-leisure domains.
• Household and outdoor activities contribute significantly to overall physical exertion.
• Previous studies may underestimate PA levels by focusing solely on leisure-time activities.

Purpose of the Study:

• To quantify physical activity (PA) in healthy middle-aged women.
• To assess adherence to the Centers for Disease Control (CDC) PA guidelines across multiple activity domains.
• To investigate the impact of including household and outdoor activities on PA guideline attainment.

Main Methods:

• A cohort of 440 healthy women aged 51-64 years participated.
• Body Mass Index (BMI) was within the range of 18.5 to 40 kg/m².
• The Lifetime Physical Activity Questionnaire (LPAQ) was used to measure PA.

Main Results:

• Only 25.91% of women met CDC PA guidelines when considering leisure activities alone.
• Inclusion of household and outdoor activities raised guideline adherence to 73.41%.
• This adherence rate is substantially higher than the 20.6% reported for U.S. adults in 2011.

Conclusions:

• Physical activity in middle-aged women is significantly underrepresented when limited to leisure-time pursuits.
• A comprehensive assessment including household and outdoor activities reveals higher PA guideline adherence.
• Public health recommendations and research should incorporate diverse PA domains for accurate representation.
