Seasonal variation in physical activity in patients with heart failure

Background and objectivesPhysical activity is important for all heart failure (HF) patients to improve quality of life and physical function. Since adherence to physical activity is low and could differ between seasons, it is essential to explore factors related to change that may depend on seasonal changes. The purpose of this study was to describe the seasonal differences in physical activity and assess factors that influence these differences in a country with markedly different winter-to-summer weather conditions (in temperature, hours of daylight and snow fall).MethodsThe study had a cross-sectional survey design. Outpatients with HF completed a questionnaire on physical activity, motivation and self-efficacy to exercise and HF symptom severity in the summer and the winter in a northern hemisphere country. We used analysis of variance to evaluate seasonal differences in physical activity, motivation, self-efficacy and HF symptom severity.ResultsEighty-seven patients with HF (29% women, mean age 70 ± 9 years) were included and 35% performed less physical activity (METs) in the winter, compared to the summer. Increased symptom severity during the winter was associated with lower activity levels.ConclusionOne-third of the patients performed less physical activity during the winter compared to the summer, and this was associated with symptom severity. Decreased physical activity was not related with motivation and self-efficacy. This study emphasises the need for personalised physical activity programmes that also assess symptom severity and change in symptom severity depending between seasons.     

The association between dietary antioxidants and adipokines level among obese women

AimAdipokines are associated with several oxidative stress-related diseases and pathologic conditions. We aimed to assess the association between antioxidants and adipokines in obese adults.Methods and MaterialsIn this cross-sectional study, a total of 160 obese women were included. Body composition and anthropometric characteristics were measured. Dietary intakes were assessed by 3-day, 24-h dietary recall. Blood samples were obtained following an overnight fasting. Serum concentrations of adipokines including progranulin, retinol binding protein 4 (RBP4) and Angiopoietin-related growth factor 6 (ANGPTL6) was measured using an enzyme-linked immunosorbent assay. ANCOVA and the linear regression model analysis was performed to assess the relationship between Progranulin, RBP4, AnGPTL6, and antioxidants.ResultsMean age of included women was 39.31 ± 12.10. Mean and standard deviation for BMI was 35.05 ± 4.26 in this obese population. There was a positive significant association between ANGPTL6 and vitamin D intake (p < 0.001). Also, there was a marginal association between RBP4 and vitamin A (p = 0.063) intake, but after adjustment age, and fat mass, we found a significant association (p = 0.008). However, the associations between dietary antioxidants, progranulin, and ANGPTL6 were not statistically significant.ConclusionsANGPTL6 and RBP4 levels directly associated with dietary vitamins D and A intake, respectively. But, according to the results, the association between ANGPTL6 and vitamin D was bidirectional. The suggested associations probably can be useful in the development of interventional studies for management of chronic diseases.     

Physical activity,sedentary behaviors and dietary patterns as risk factors of obesity among Jordanian schoolchildren

ObjectiveTo identify certain risk factors associated with childhood obesity related to lifestyle; dietary patterns, physical activity, and sedentary behavior.MethodsA cross-sectional study was conducted among 977 schoolchildren (473 boys and 449 girls) aged 7–18 years. Children were selected randomly from three main cities in Jordan: Amman, Irbid, and Mafraq by using multistage cluster sampling method. Sedentary behaviors, physical activity and child eating behaviors were measured by using validated questionnaires. Overweight and obesity were defined by International Obesity Task Force (IOTF) criteria.ResultsSedentary activities increase the risk of overweight among schoolchildren by 2-fold [RR(Relative risk) = 2.0, 95% CI(Confidence interval) (1.1–3.6), p = 0.02]. Whereas, sedentary activities for less than 3 h increased the risk of overweight by 0.8-fold [RR = 0.8, 95%CI (0.6–1.3), P = 0.388], Schoolchildren who spent<30 min/day in exercising decreased the risk of overweight by 0.5-fold [RR = 0.5, 95% CI (0.2–1.0), P = 0.06)]. Both Students who ate one meal daily and daily ate snacks from schools cafeterias had a higher tendency to be obese [(RR = 1.8, 95%CI (0.5–5.9), P = 0.368], and [RR = 1.5, 95%CI (0.9–2.5), P = 0.169] respectively.ConclusionsPhysical activity, eating meals regularly and homemade food, all together play a significant role in decreasing obesity among Jordanian schoolchildren, thus a national policy that promoting active living and healthy eating among schoolchildren is warranted.     

Incidence of obesity,overweight and hypertension in children and adolescents in Ahvaz southwest of IRAN: Five-years study

ObjectiveThe purpose of this study was to investigate the incidence of obesity, overweight and hypertension in children and adolescents aged 10–15 in Ahvaz.MethodsThis is a epidemiologic study performed on 176 people aged 10–15 in Ahvaz. In 2009, 300 people underwent weight, height and blood pressure measurements. Five years later, the same people were reassessed for obesity, overweight and hypertension, of whom a total of 176 people agreed to repeat the procedure.ResultsThe study included 100 (57%) males and 76 (43%) females. Mean BMI was 22.1 ± 4.3 kg / m2 in year 2014, without any significant difference between the two sexes (P = 0.518). In the same year, the prevalence of obesity and overweight was 26 (14.8%) and 13 (7.4%), respectively. After 5years, BMI increased significantly (P < 0.001). Of the 150 norma participants with normal BMI in 2009, 15 (10%) and 6 (4%) became overweight and obese in 2014 respectively. The mean systolic and diastolic blood pressures increased significantly over 5 years P = 0.042 and P < 0.001.ConclusionsThis study shows an increase in mean BMI and mean systolic and diastolic blood pressures after 5 years among people aged 10–15 in Ahvaz.     

Prevalence of overweight and obesity in the adult indigenous population in Brazil: A systematic review with meta-analysis

To carry out a systematic review to identify the prevalence of overweight and obesity in the adult indigenous population in Brazil. The databases used were PubMed, Scopus, Virtual Health Library (VHL), and Science Direct, with the following search strategy: “overweight” OR “obesity” AND “indigenous” OR “tribe” AND “Brazil”. For the meta-analysis, RStudio^® software was used. Were 22 articles included. The combined effect of the meta-analysis studies showed a global prevalence of overweight and obesity of 45%. Approximately half (45%) of indigenous Brazilian adults have excess weight. These findings highlight the need to implement public policies for the prevention and treatment of these morbidities.

Colon transit time according to physical activity and characteristics in South Korean adults

AIM:To investigate factors contributing to the colon transit time(CTT),physical activity and characteristics were examined.METHODS:Forty-seven Korean adults(males,n=23;females,n=24) took a capsule containing 20 radioopaque markers to measure the CTT.The subjects used an accelerometer to measure the physical activity and underwent a bioelectrical impedance analysis to determine the physical characteristics.Macro-nutrient was also surveyed.RESULTS:The mean total CTTs(TCTT) in the males and females were 8.8 and 24.7 h(P=0.002),respectively.In the male subjects,the right CTT(3.5±4.9 h vs 10.0±11.6 h,P=0.023) and recto-sigmoid CTT(4.4±4.7 vs 13.6±12.5 h,P=0.004) were significantly shorter and the total energy expenditure(637.6±44.3 kcal vs 464.3±64.9 kcal,P=0.003),total activity count(247 017±75 022 count vs 178 014±75 998 count,P=0.003),energy expenditure of light intensity(148.5±6.9 kcal vs 120.0±16.8 kcal,P=0.006),energy expenditure of moderate intensity(472.0±36.2 kcal vs 281.4±22.2 kcal,P < 0.001),fat intake(65.5±23.3 g vs 51.2±17.4 g,P=0.010),and water consumption(1714.3±329.4 g vs 1164.7±263.6 g,P=0.009) were significantly higher than in the female subjects.Regarding correlations,when adjusted for gender,fiber(r =-0.545,P < 0.001) and water intake(r =-0.257,P < 0.05) correlated significantly with the TCTT in all subjects.In addition,the body mass index(r =-0.424,P < 0.05) and fiber intake(r =-0.417,P < 0.05) in the males as well as the fiber intake(r =-0.655,P < 0.001) in the females showed significant correlations with the TCTT.CONCLUSION:The subjects showed significant gender differences in the TCTT,right CTT,and recto-sigmoid CTT.Furthermore,the intake of the fiber and water contributed to the CTT.     

Association of FTO rs1421085 with obesity,diet, physical activity,and socioeconomic status: A longitudinal birth cohort study

Background and aimsFat mass and obesity-associated protein (FTO) variants are among genetic variants frequently associated with obesity. We analyzed the association between FTO rs1421085 polymorphism and obesity, dietary intake, cardiorespiratory fitness (CRF), physical activity, and socioeconomic status (SES) from the age of 9–25 years.Methods and resultsThe sample included both birth cohorts (originally n = 1176) of the Estonian Children Personality Behaviour and Health Study. The association between FTO rs1421085 and obesity, dietary intake, CRF, physical activity, and SES from the age of 15–25 years was assessed using linear mixed-effects regression models. Associations at ages 9 (younger cohort only), 15, 18, and 25 years were assessed by one-way ANOVA. Male C-allele carriers had significantly (p < 0.05) higher body mass index (BMI), sum of 5 skinfolds, body fat percentage, and hip circumference from the age of 15–25 years. Findings were similar at the age of 9 years. In female subjects, waist-to-hip ratio was significantly greater in CC homozygotes. Interestingly, female CC homozygotes had a greater decrease in the rate of change in daily energy intake and lipid intake per year and higher physical activity score at every fixed time point. Moreover, in females, an effect of FTO × SES interaction on measures of obesity was observed.ConclusionThe FTO rs1421085 polymorphism was associated with obesity and abdominal obesity from childhood to young adulthood in males, and with abdominal obesity from adolescence to young adulthood in females. This association is rather related to differences in adipocyte energy metabolism than lifestyle.     

Adiposity,physical fitness and incident diabetes: the physical activity longitudinal study

Aims/hypothesis The purpose of this study was to investigate the relationships among adiposity, physical activity, physical fitness and the development of diabetes in a diverse sample of Canadians. Methods The sample included 1,543 adults (709 men and 834 women) from the Canadian Physical Activity Longitudinal Study who were free of diabetes at baseline (1988). Several indicators of adiposity (BMI, waist circumference, WHR, sum of skinfold thicknesses), musculoskeletal fitness (sit-ups, push-ups, grip strength, trunk flexibility), cardiorespiratory fitness (maximal metabolic equivalents [METs]) and leisure-time physical activity levels were measured at baseline. Participants were followed until 2002–2004 for the ascertainment of new cases of diabetes. Results The 15.5-year cumulative incidence of diabetes was 5.0% (5.2% in men, 4.9% in women). Adiposity and physical fitness, but not physical activity, were significant predictors of diabetes after adjustment for age, sex and several covariates. For each standard deviation of the indicators of adiposity, the risk of diabetes was 99–194% higher. Conversely, the risk was 70 and 61% lower for each standard deviation of maximal METs and composite musculoskeletal fitness score, respectively. Receiver operating characteristic curve analyses confirmed that neither adiposity nor physical fitness provided a superior prediction of incident diabetes. Conclusions/interpretation Adiposity and physical fitness were both important predictors of the development of diabetes in this cohort of Canadians.     

Age modify the associations of obesity,physical activity,vision and grip strength with functional mobility in Irish aged 50 and older

ObjectiveTo estimate whether the associations of obesity, physical activity, vision and grip strength with functional mobility were modified by age.MethodsData from The Irish Longitudinal Study on Ageing (2009–2012) were analyzed and 5001 individuals were included in this study. Mobility was assessed by the timed up and go test (TUG-test). Main exposure variables were obesity, physical activity, visual acuity and grip strength at baseline. Multiple linear regression models were fitted to assess the associations of baseline main exposure variables with 2-year follow-up functional mobility and potential confounders were adjusted. Stratified analyses by age were used to assess the interaction between main exposures and age on functional mobility.ResultsMultiple linear regression models identified significant interactions of obesity (P < 0.001), vigorous physical activity (P = 0.001), vision (P < 0.001) and grip strength (P < 0.001) with age on functional mobility. Stratified analyses suggested that the risk effect of obesity on functional mobility was greater in middle-aged group (β = 0.025, P < 0.001) than in older group (β = 0.016, P = 0.017). The protective effects of high level of physical activity and grip strength on functional mobility were stronger in older group (β = −0.023, P = 0.004 for physical activity; β = −0.002, P < 0.001 for grip strength) than in middle-aged group (β = −0.012, P = 0.008 for physical activity; β = −0.0015, P < 0.001 for grip strength). The benefit of better vision on functional mobility was observed in middle-aged group only (β = −0.032, P = 0.002).ConclusionNon-obesity, higher level of physical activity, vision and grip strength at baseline were associated with better mobility performance among middle-aged and older Irish. And these associations were modified by age.     

The Association between time spent in performing physical activity and physical function in outpatients with type 2 diabetes who may have diabetic neuropathy

AimsTo determine the relationship between physical activity time and physical function according to the Japanese Clinical Practice Guideline for Diabetes, which recommended 150 min of activity for outpatients with type 2 diabetes who may have diabetic neuropathy.MethodsWe examined a cross-sectional study with 79 outpatients with Type 2 diabetes participated. A short version, Japanese language edition of the International Physical Activity Questionnaire (IPAQ) was used to evaluate physical activity. Isometric knee extensor strength, grip strength, maximum 10-m walking speed, the Michigan Neuropathy Screening Instrument score, and the Short Physical Performance Battery (SPPB). Each evaluation item was compared between time spent performing physical activity ≥150 min group and <150 min group, and multiple regression analysis was performed to determine the factors associated with time spent performing physical activity. Further, the correlation between time spent performing physical activity and isometric knee extensor strength was examined.ResultsThe ≥150 min group had significantly higher isometric knee extensor strength than the <150 min group. In addition, the ≥150 min group had significantly faster maximum 10-m walking speed and sit-to-stand time than the <150 min group. Isometric knee extensor strength was determined to be an independent factor associated with the IPAQ score. A positive correlation was found between the IPAQ score and isometric knee extensor strength.ConclusionsAmong the patients with type 2 diabetes who may have diabetic neuropathy, those who performed physical activity for ≥150 min per week were suggested to have higher physical function than those with <150 min of activity.     

Association between hypertension and adiposity indicators: A study among the Muslim population of Uttar Pradesh

BackgroundHypertension and obesity have become a global issue and an important public health concern due to an unhealthy lifestyle. The present study aims to determine the prevalence of hypertension and its association with various adiposity indicators among Sunni Muslim population of Lucknow, Uttar Pradesh.Materials and methodsA cross-sectional study was conducted among 214 individuals using purposive sampling method. Somatometric measurements were taken using the ISAK protocol. Correlation analysis and odds ratio were calculated to determine the best predictor of hypertension.Results41% of males and 42.1% of females were found to be in Stage-II hypertension. BMI and WC were found to have the highest correlation with SBP among males and females, respectively. WHR followed by WC and BMI, was found to be the strongest predictor of hypertension in males. In the case of females, WHtR Followed by, BMI and WHR were found to be the strongest predictors of hypertension.ConclusionAmong the presently studied Muslim population of Lucknow, a high prevalence of hypertension was found among both males and females. Also, WHR among males and WC among females were found to be better predictors of hypertension. Thus, for better prediction of risk of hypertension, sex and ethnicity-specific adiposity indicator should be used in clinical practice.     

Beneficial effects of moderate to vigorous physical activity on cardiovascular disease among Chinese adults

Background In China, lack of evidence remains a significant challenge for the national initiative to promote physical activity (PA). We aimed to quantify the beneficial effects of meeting or maintaining the recommended PA level [150 minutes per week (min/wk) of moderate PA or 75 min/wk of vigorous PA or an equivalent combination] on incident cardiovascular disease (CVD) among Chinese population. Methods We included 100,560 participants without history of CVD from three cohorts in the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) project. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for CVD events and its subtypes, including stroke, coronary heart disease, heart failure, and CVD death. Results During a median follow-up of 7.3 years (range: 6–15 years), 777,163 person-years and 4693 incident CVD events were observed. Compared with participants who were inactive at baseline, the multivariable adjusted HR (95% CI) of developing CVD was 0.74 (0.69–0.79) for those who met recommended moderate to vigorous physical activity (MVPA) level at baseline. Furthermore, the risk of CVD incidence was reduced with increment of MVPA (Ptrend Conclusions The findings demonstrated that meeting and maintaining the recommended MVPA level could reduce the cardiovascular risk. Wider adoption of the PA recommendations would have considerable health impacts to the Chinese population.     

Bidirectional associations of accelerometer-assessed physical activity and sedentary time with physical function among older English adults: the EPIC-Norfolk cohort study

To develop healthy ageing interventions, longitudinal associations between objectively assessed physical behaviours and physical function need to be better understood. We assessed associations between accelerometer-assessed total physical activity (PA), moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), sedentary time and prolonged sedentary bout time, and clinically assessed physical function (grip strength, usual walking speed (UWS), chair stand speed) at two time-points in 3188 participants (≥ 60 years) of the EPIC-Norfolk study. Bidirectional associations were assessed using multivariable linear regression. Over an average of 6.1 years, baseline physical behaviours (greater total PA, MVPA and LPA, and less sedentary time) were associated with better subsequent walking and chair stand speed. Better baseline physical function was associated with better follow-up physical behaviours. There were no bidirectional associations between changes in physical behaviours and grip strength. Improvements in UWS were associated with improvements in all physical behaviours. Improvements in chair stand speed were associated with improvements in total PA, MVPA, and sedentary bout time. Improvements in physical behaviours were associated with improvements in UWS (3.1 cm/s/yr per 100 cpm/yr  total PA, 3.6 cm/s/yr per hr/day/yr MVPA, 2.5 cm/s/yr per hr/day/yr LPA, − 2.9 cm/s/yr per hour/day/yr sedentary time, and − 1.6 cm/s/yr per hr/day/yr prolonged sedentary bout time). Only improvements in total PA, MVPA and sedentary bout time were associated with improvements in chair stand speed. In conclusion, we found bidirectional associations between changes in some physical behaviours and physical function and between baseline physical behaviours and subsequent physical function, highlighting the importance of considering the full range of physical behaviours to promote healthy ageing.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10433-022-00733-y.     

Combined effects of obesity and physical activity in predicting mortality among men

Objective. We evaluated the hypothesis that higher levels of total daily physical activity can eliminate the increased mortality rate associated with overweight and obesity. Design. Population‐based prospective cohort study. Setting. Central Sweden. Subjects. A total of 37 633 men at baseline 45–79 years of age and free of known cancer and cardiovascular disease and diabetes completed a self‐administered life‐style questionnaire, which included questions on body‐mass index (BMI) and physical activity . During 9.7 years of follow‐up, we identified a total of 4086 deaths. Main outcome measures. Mortality rate ratios (RRs). Results. Compared to men who were lean (BMI < 25 kg m^?2) and active (top tertile of total physical activity level) the multivariable adjusted RRs (95% confidence interval) of death from all causes were 1.44 (1.11–1.86) for obese (BMI ≥ 30 kg m^?2) and active men, 1.54 (1.34–1.77) for lean (BMI < 25 kg m^?2) but inactive (bottom tertile) men, and 1.81 (1.48–2.23) for obese‐inactive men. After excluding the first 3 years of follow‐up, current and former smokers, those who had lost weight from age 20 years to age at baseline, and heavy manual workers, the adjusted RRs of death from all causes were 1.65 (1.20–2.27) for overweight‐to‐obese and active men, 2.15 (1.59–2.91) for lean‐inactive men, and 2.04 (1.52–2.74) for overweight‐to‐obese and inactive men compared to lean‐active men. Conclusions. We conclude that both overweight and physical inactivity are important predictors of mortality. Our findings do not support the hypothesis that a higher level of physical activity compensates the excess mortality associated with overweight and obesity.     

An update on physical health and economic consequences of overweight and obesity

Overweight and obesity (OW and OB) have been on the increase globally and posed health risks to the world’s population of all ages, including pre-born babies, children, adolescents, adults and elderly people, via their comorbid conditions. Excellent examples of comorbidities associated with obesity include cancer, cardiovascular diseases (CVD) and type 2 diabetes mellitus (T2DM). In this article, we aimed to review and update scientific evidence regarding the relationships between obesity and its common physical health consequences, including CVD, T2DM, hypertension, ischemic stroke, cancer, dyslipidemia and reproductive disorders. In addition, the economic burden of OW and OB will be discussed. Abundant evidence is found to support the associations between obesity and other diseases. In general, the odd ratios, risk ratios or hazard ratios are often higher in OW and OB people than in the normal-weight ones. However, the molecular mechanism of how OW and OB induce the development of other diseases has not been fully understood. Figures also showed that obesity and its-related disorders exert enormous pressure on the economy which is projected to increase. This review highlights the fact that obesity can lead to numerous lethal health problems; therefore, it requires a lot of economic resources to fight against this epidemic.     

A pilot structured behavioural intervention trial to increase physical activity among women with recent gestational diabetes

Increases in achievement of physical activity targets were not attained. Recruitment and subject retention were identified as major challenges.     

General obesity and Cardiovascular diseases among Gaur Brahmin population of NCR/Delhi

AimsCardiovascular diseases are one of the leading causes of mortality and morbidity among human beings. The presence of endemic Cardiovascular diseases and their risk factors differ from population to population. The Cardiovascular diseases associated risk factors are sub-categorised into two forms, one is traditional and the other is non-traditional risk factors. The present study shows the prevalence of both risk factors and its association with Cardiovascular diseases, especially with reference to general obesity.Materials and methodsThe present study includes a total of 506 Gaur Brahmins residing in Delhi and National Capital Region India. Household survey was conducted and data were collected by using pre-tested interview schedule. Somatometric measurements were taken following the international standard techniques. Approx 5 ml blood was collected from each individual unrelated up to the first cousion. The serum was used to analyse the lipid profiles and fasting glucose level. All necessary statistical analyses were performed using the Statistical Package for Social Sciences (SPSS) and MS Excel. The ethical clearance was obtained from the Ethical Committee of the Department of Anthropology, University of Delhi, Delhi.Results and conclusionThe mean value of Somatometric variables such as Body Mass Index, Waist circumference and Waist-hip ratio and physiological variables DBP and SBP (diastolic blood pressure and systolic blood pressure) were found to be higher than their respective ranges in the studied population. General obesity, though found to be less common in this population as compared to abdominal obesity, but it is found to be contributing to dyslipidemia.
