Trends in Meeting the Physical Activity Guidelines: Muscle-Strengthening Alone and Combined With Aerobic Activity, United States, 1998–2018

Abstract

Background: The National Health Interview Survey is unique among US federal surveillance systems with over 20 years of consistent assessment of muscle-strengthening and aerobic activity. The authors examined trends in the prevalence of US adults who met the muscle-strengthening (2 or more days per week) and the combined muscle-strengthening and aerobic physical activity (at least 150 min/wk of moderate-intensity equivalent activity) guidelines from 1998 to 2018. Methods: The 1998–2018 National Health Interview Survey data were analyzed. Age-adjusted prevalence of meeting the muscle-strengthening and combined aerobic and muscle-strengthening guidelines by selected respondent characteristics were estimated for each year and linear and higher-order trends were assessed. Results: From 1998 to 2018, prevalence of meeting the muscle-strengthening guideline increased from 17.7% to 27.6%, and meeting the combined aerobic and muscle-strengthening guidelines increased from 14.4% to 24.0%. All subgroups demonstrated significant increases in meeting both guideline measures over this period although trends varied across the 21 years; increasing trends were more commonly sustained in the second decade of monitoring. Conclusions: Although increasing trends in prevalence of meeting the muscle-strengthening and combined guidelines are encouraging, current prevalence estimates remain low. Opportunities exist for the continued promotion of muscle-strengthening activity using evidence-based approaches.

Daily Fluid Intake Behaviors and Associated Health Effects Among Australian and United States Populations

“…This was observed in this study with fluid volume [2,662 ± 1,444 ml; t (487) , 2.660; p = 0.008] and water intake [1,796 ± 1,156 ml; t (487) , 3.679; p < 0.001] greater in those who completed >150 min of moderate–vigorous physical activities per week. Observational trends in those who meet the Physical Activity Guidelines for Americans show a 9.6% increase from 1998 to the latest report released by the CDC in 2018 (Hyde et al, 2021 ). Increases in total FI and shifts in fluid preference to water intake may be related to an increase in physical activity.…”

Differences in Physical Activity According to Age and Depression: Based on the 2014-2017 Korea National Health and Nutrition Examination Survey

“…The reason why there was no difference in the number of days of strength training in the depressed and non-depressed groups is not that strength training has no effect on depression, but rather that the exercise rate itself is low in the elderly. In this regard, in order to increase the participation rate in muscle-strengthening activities in the future physical activity promotion strategy, it was suggested that adults over 65 years of age should be selected as a priority group [24].…”

BMI and Physical Activity, Military-Aged U.S. Population 2015–2020

“…22,24 Meanwhile, more adults aged 18−44 years are meeting the combined aerobic and muscle-strengthening physical activity guidelines in leisure time, but the 2018 prevalence remained below 25%. 25 The impact of these trends on military preparedness is unknown. The most recently published manuscript on the topic used 2007−2008 data.…”
