Association of Sedentary Time and Physical Activity with the 10-Year Risk of Cardiovascular Disease: Korea National Health and Nutrition Examination Survey 2014–2017

Abstract

Background: Sedentary behavior is associated with increased cardiovascular disease (CVD) risk. We investigated this association of sedentary time and physical activity with increased 10-year CVD risk in Korean adults. Methods: This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (2014-2017). In total, 14,551 participants aged 30-74 years (6,323 men, 8,228 women) were analyzed. The usual length of sedentary time per day was categorized into three groups (<6, 6-<9, or ≥9 h/d), and physical activity (metabolic equivalents [METs]•min/wk) was categorized into two groups (low, <600 METs•min/wk; moderate/high, ≥600 METs•min/wk). Logistic regression analysis was performed to assess the association between sedentary time and increased CVD risk (predicted 10-year risk ≥10%). Adjusted variables were age, sex, body mass index, marital status, employment, household income, alcohol use, family history of CVD, and comorbidity (hypertension, diabetes, and dyslipidemia). Results: The average sedentary time for the 14,551 participants was 7.49 h/d, with an average 10-year CVD risk of 9.58%. There was no significant association between sedentary time and increased 10-year CVD risk in the moderate/high physical activity group. In the low physical activity group, sedentary time ≥9 h/d had a significant association with increased CVD risk (odds ratio [OR], 1.29; 95% confidence interval [CI], 1.04-1.62). However, when the sedentary time was <6 h/d, no significant associations were found (OR, 1.17; 95% CI, 0.92-1.49). Conclusion: In the low physical activity group, reduction of sedentary time might be important for preventing increased CVD risk.

Sedentary Lifestyle: Overview of Updated Evidence of Potential Health Risks

“…In the group with more physical activity, sedentary time was not significantly associated with CVD risk. 52) In other words, while increased sedentary time increases the mor- all-cause mortality when it was greater than 7 MET/h, and for television viewing, when it was greater than 3 MET/h. The mean increase in mortality per USMh was 1% (RR, 1.01; 95% CI, 1.00-1.02; P=0.01), and the mean increase in mortality per USMh for TV watching was 7% (RR, 1.07; 95% CI, 1.04-1.10; P<0.001).…”

“…Similarly, a study showed that a sedentary time of over 9 hours per day in the low physical activity group (<600 METs-min/wk) had a significant association with an increased CVD risk (OR, 1.29; 95% CI, 1.04–1.62). In the group with more physical activity, sedentary time was not significantly associated with CVD risk [ 52 ].…”

“…Em uma análise que correlaciona o tempo de sedentarismo, a prática de exercício físico e o risco de doença cardiovascular (DCV), tempos acima de 6 hora por dia sem atividade, há um risco aumentado para desenvolver a DCV em 10 anos, diferente do grupo que possui atividades ocupacionais não foi observado o aumento do risco em estudos longitudinais (Lee, Y et al, 2020).…”

“…The WHO recommended standard for PA in adults is ≥ 150 minutes of moderate-intensity activity per week or ≥ 75 minutes of vigorous-intensity activity per week. 17 Therefore, those who engaged in ≥150 minutes of moderate-intensity activity per week or ≥ 75 minutes of vigorous-intensity activity per week were defined as participants of PA in both OPA and LTPA. 18 TPA was defined as physical activity such as walking or cycling for ≥ 150 minutes per week when moving from place to place, except for work-related movement.…”
