Gender Differences in the Effects of the Frequency of Physical Activity on the Incidence of Metabolic Syndrome: Results from a Middle-Aged Community Cohort in Taiwan

Sex and Age Differences in Association between Physical Activity and Metabolic Syndrome: Results from NHANES 2003-2006

OBJECTIVE

To examine whether and how sex and age modify the association between accelerometer-based physical activity (PA) and metabolic syndrome (MetS) among American (US) adults.

METHOD

Adults aged ≥20 years old who participated in the mobile center examination during 2003-2006 in the National Health and Nutrition Examination Survey were included for analysis. The total minutes per day of moderate-to-vigorous PA (MVPA) was estimated using ActiGraph. Multivariable logistic regression was used to estimate the odds ratio (OR) of having MetS at an increasing MVPA time. The modification effects of gender and age on the association between MetS and MVPA time were examined by testing for two-way and three-way interaction terms of MVPA time, sex, and age in the model after adjusting for relevant covariates.

RESULTS

The prevalence of MetS generally decreased with the MVPA time and was lower in females than in males, although the sex difference varied across age groups. After adjusting for demographic and lifestyle covariates, there was a significant sex difference in how an increased MVPA time lowered the odds of MetS. This interactive effect also varied with age. MVPA benefitted young and middle-age populations up until about 65 years old for both sexes, and the protective effect weakened with age. Although the effect of MVPA was stronger for males than females at young ages, the rate at which it attenuated was quicker in males. The OR of MetS between males and females per unit change of MVPA time was 0.73 (95% CI: [0.57, 0.93]) at age = 25 years, compared to OR = 1.00 (95% CI: [0.88, 1.16]) at age = 60 years. Before the age of 50, the gender difference in the protective effect on MetS was larger at low MVPA levels and became smaller at higher MVPA levels. The male advantage was quite stable with an increasing MVPA time for ages 50-60, and no longer significant at older ages.

CONCLUSIONS

Young and middle-age populations benefitted from MVPA, lowering the risk of MetS for both sexes. A longer MVPA time was associated with a greater decrease in the risk of MetS in young men than in women, but the sex difference reduced with age and was no longer apparent in older populations.

Active Physical Activity Patterns Are Associated With Improved Quality of Life and Depression Status in Taiwanese Women With Metabolic Syndrome

BACKGROUND

Metabolic syndrome (MetS), health-related quality of life (HRQL), and depression status are independently associated with cardiac health. Therefore, understanding the associations between MetS, HRQL, and depression status and determining factors related to improved HRQL and depression status in people with MetS may help in cardiovascular disease prevention.

OBJECTIVE

The aim of this study was to examine whether there are differences in HRQL and depression status between Taiwanese women with and without MetS and whether physical activity patterns are associated with HRQL and depression status in this population.

METHODS

A cross-sectional study of 326 Taiwanese middle-aged and older women (≥40 years) was conducted. Metabolic syndrome was determined based on the National Cholesterol Education Program Adult Treatment Panel III definition. Health-related quality of life and depression status were collected using the Short Form 36 Health Survey and Beck Depression Inventory. Univariate and multivariate linear regression analyses were conducted.

RESULTS

Women with MetS had lower HRQL (P < .001) and higher depression status (P = .002) than those without MetS. Participants with active physical activity patterns had higher HRQL (P < .001) and lower depression status (P = .046) than those with sedentary patterns. Among women with MetS, those with active physical activity patterns had higher HRQL (P = .001) and lower depression status (P = .007) than those with sedentary patterns.

CONCLUSIONS

Metabolic syndrome is related to lower HRQL and higher depression status in women 40 years and older. Active physical activity patterns are associated with better HRQL and reduced depression status in middle-aged and older women (≥40 years) with MetS.

Metabolic syndrome and its associations with socio-demographic and behavioral risk factors in the Russian population aged 25-64 years

Aim. To assess the associations of metabolic syndrome (MS) with sociodemographic and  behavioral factors  in the  Russian population  aged 25-64 years.

Material and methods. As part of the ESSE-RF 2 study, representative samples of the population of four Russian regions (Krasnodar Krai, Omsk and Ryazan Oblasts, Republic of Karelia) were examined: men (n=3011) and women (n=3721) aged 25-64 years. The response rate was approximately 80%. The study was approved by the Independent Ethics Committee of National Medical Research Center for Therapy and Preventive Medicine. All subjects were interviewed using a standard questionnaire. We analyzed the region and type of residence (urban/ rural area), age, educational level, marital and economic status, behavioral habits, and medical history data. Anthropometric measurements were performed. Blood pressure (BP) was measured with an Omron BP monitor. Lipid profile were assessed. MS was diagnosed according to the IDF criteria (2006). Statistical analysis was performed using the R 3.6.1 software package.

Results. Abdominal obesity (AO) was found in 49,7% of men and 61,6% of women. Obesity according to body mass index was noted in 31,6% of subjects (men — 28,6% and women — 34%). MS prevalence in the entire sample was 33,0% and increased with age. In the group of subjects 35-44 years old, the prevalence of MS was significantly higher among men, and among those 55-64 years old — among women. We also found that AO in combination with two MS components was observed in 17,2% of participants; AO  with three components  — in 11,8%, AO with four components — in 4%. The highest prevalence of MS was noted in theRyazan region (men — 42,0%, women — 37,4%), the lowest — in theRepublic ofKarelia (men — 25,8%, women — 29,6%). In men, age-adjusted univariate logistic regression revealed significant associations of MS with former smoking, low physical activity, and alcohol abuse. Elevated BP and lipid profile abnormalities were significantly associated with low income level. AO was significantly associated with marriage. Similarly, the risk of diabetes and elevated blood glucose levels was lower in single men. Among women, the risk of MS was higher in those without higher education, with low income, smoking, and low consumption of vegetables and fruits. Women living in rural areas have a higher risk of AO and high BP. The risk of lipid metabolism disorders was higher among women with secondary education. Most of these associations were confirmed by multivariate analysis.

Conclusion. MS was diagnosed in 33% of Russians aged 25-64 years. The proportion of people with MS increases with age, which, due to the  life expectancy increase, suggests an increase in the total number of MS people. Risk factors associated with MS in women are smoking, insufficient consumption of vegetables and fruits, no higher education, and low income. In men, MS are associated with excessive alcohol consumption, smoking, and low physical activity. MS prevalence can be reduced by changing the lifestyle and habits, and if necessary, in combination with drug therapy.

Domain and intensity of physical activity are associated with metabolic syndrome: A population-based study

Introduction

Little is known on how the domain and intensity of physical activity (PA) associates with metabolic syndrome (MetS). The aim of this study was to examine associations between PA domains (leisure-time, domestic, active transport, total walking and total PA), PA intensities (light, moderate and vigorous) and PA levels with MetS in the general adult population.

Methods

Cross-sectional study. Anthropometry, blood biochemistry, 79-item PA-questionnaire, lifestyle and medical history were evaluated in a representative sample of Canary Island adults (n = 6,729). MetS was diagnosed using the harmonized IDF-NHLBI-AHA criteria. T-test and multivariable logistic regression was used to analyse associations between PA domains and intensities with MetS vs. no MetS, controlling for socio-demographic, lifestyle, family antecedents and body mass index (BMI).

Results

For each MET-h/day spent in moderate-vigorous PA intensities, as well as in recreational domain, active transport, total walking and total PA, the odds of MetS decreased between 3–10%. Energy expenditure exclusively in light and domestic PAs was not associated with MetS, however it was important to achieve a total PA level of 3 MET-h/day, which reduced the odds of MetS by 23%. This reduction was blunted in those with more than 2 h/d of TV watching time. A PA level of 3 MET-h/d also nullified the risk of MetS in those with low PA and high TV consumption.

Conclusions

Some types of leisure time PAs may contribute more than others to reducing MetS. Light and domestic PA play a complementary role in enhancing energy expenditure in the general population. TV watching time above 2 h/d counteracted the MetS risk reduction associated with PA level, but PA level also reduced the risk of METs presented by those with a low level of PA and an excess TV watching time. Physical activity explains a greater amount of the variance of MetS than any other factors of lifestyle, education, sex and family history, and substantially mitigates the strong association of age and BMI with MetS.

Gender differences in lifestyle and risk factors of metabolic syndrome: Do women have better health habits than men?

AIMS AND OBJECTIVES

To examine the gender-specific lifestyles of adults with metabolic syndrome in the Taiwanese community.

BACKGROUND

Many studies show different prevalence of metabolic syndrome in males and females; however, few studies have investigated gender-specific lifestyle risk factors, which are important for effectively reducing prevalence.

DESIGN

A cross-sectional study design was used.

METHODS

Between 2012 and 2015, a total of 1,066 individuals were recruited in northern Taiwan. Data were collected by questionnaires and analysed by descriptive statistics, chi-square tests and logistic regression. This study followed the STROBE guidelines.

RESULTS

The prevalence of metabolic syndrome was 40.8% in men and 36.0% in women. Women had healthier dietary habits, a higher rate of moderate-vigorous physical activity, and a lower rate of smoking and obesity than men. Men, who were overweight or obese, lacked vigorous physical activity, often consumed excess amounts of salt and fat, and seldom consumed appropriate amounts of protein tended to have metabolic syndrome. Women with an unhealthy metabolism tended to be overweight or obese and seldom consumed dairy products.

CONCLUSIONS

Men, who had normal body weight, performed vigorous physical activity, seldom consumed excess amounts of salt and fat, and often consumed appropriate amounts of protein tended not to have metabolic syndrome. Women with a healthy metabolism were of normal body weight and often consumed dairy products. There exist gender differences in health habits with metabolic syndrome.

RELEVANCE TO CLINICAL PRACTICE

Although the associated risk factors differed between men and women, controlling body weight and maintaining a healthy lifestyle may reduce the risk of metabolic syndrome.
