Gender Differences in the Association between Sleep Duration and Cardiometabolic Risk: A Cross-sectional Study

Abstract Background: Inappropriate sleep duration (shorter/longer than optimal sleep duration) has come to be identified as a potential cardiometabolic risk factor, and thereby, as a risk factor for atherosclerotic cardiovascular disease (ASCVD). Few data exist regarding the gender differences in the relationship between sleep duration and cardiometabolic risk.Methods: This cross-sectional study was conducted in a study population of 9262 apparently healthy (5004 male, 4258 female) subjects at the Health Planning Center of Nihon University Hospital between September, 2015, and October 2016.Results: In the male subjects, as compared to a sleep duration of 6 to 7 hours, a sleep duration of ³8 hours was associated with an odds ratio (OR) for abdominal obesity (defined according to the Japanese criteria for metabolic syndrome as a waist circumference of ³85 cm) of 1.31 (95% confidence interval [CI], 1.004-1.71) and for a non-high-density lipoprotein cholesterol level of ³150 mg/dL (defined as “Borderline hyper” by the Japan Atherosclerosis Society Guidelines for Prevention of ASCVD 2017) of 1.33 (1.05-1.68), and a sleep duration of <5 hours was associated with an OR (95% CI) for a fasting blood glucose of ³100 mg/dL (defined as “high” by a specialized lifestyle checkup program for the detection of symptoms of metabolic syndrome in Japan) of 1.74 (1.25-2.42). On the other hand, in the female subjects, as compared to a sleep duration of 6 to 7 hours, a sleep duration of <5 hours was associated with an OR (95% CI) for abdominal obesity (waist circumference ³90 cm) of 1.98 (1.11-3.55) and for a hemoglobin A1c (HbA1c) level of ³5.6 % of 1.52 (1.10-2.10), whereas a sleep duration of ³8 hours was not associated with worsening of any of the examined cardiometabolic risk factors. Conclusions: There may be gender differences in the relationship between sleep duration and cardiometabolic risk. To further reduce the risk of ASCVD, it may be of particular importance to emphasize adequate sleep duration.Clinical Trial Registration: UMIN (http://www.umin.ac.jp/) Study ID:　 UMIN000037643 retrospectively registered on 9 August 2019

Abstract BackgroundObesity has become a global epidemic and an important risk factor for non-communicable diseases. Earlier thought to be a problem of developed world, it has now become a problem of low- and middle-income countries like Nepal. In absence of a routine surveillance or a registry system, the actual burden and trend of obesity in Nepal is unknown. Obesity and overweight are recognized risk factors for hypertension and associated with cardiovascular disease. The aim of the study was to find out burden of obesity, using three commonly employed metrics in hospital outpatient setting of a low-income country as predictors of hypertension, and compare ability of different anthropometric measurements through a non-inferiority study to predict hypertension.MethodsThis cross-sectional study was conducted among 40-69 years outpatients in a tertiary Eye and ENT hospital in a semi-urban area of Nepal among randomly selected 2,256 participants from 6,769 outpatients who were evaluated in Health Promotion and risk factor screening service. We did correlation analysis to determine the relationship between anthropometric measurement and blood pressure. The area under the Receiver Operating characteristic curve of Body Mass Index (BMI), Waist to Height Ratio (WHtR) and Waist Circumference (WC) was calculated and compared. ResultsThe prevalence of obesity and overweight by BMI was 16.09% and 42.20% respectively; by Waist-to-Height-Ratio was 32.76% which is two times higher than obesity measured by BMI. High waist circumference was observed among 66.76% participants. Female participants had greater prevalence of high WC (77.46%) than male (53.73%) (p<0.001). Prevalence of hypertension and pre-hypertension was 40.67% and 36.77% respectively. The areas under the curve were significantly higher than 0.5 for BMI (0.593), WHtR (0.602) and WC (0.610).ConclusionWaist circumference correlated well with obesity and hypertension. It also had higher predicting ability than WHtR and BMI to predict hypertension. Waist circumference thus proved to be non-inferior to two other commonly used metrics. It proved superior in detecting obesity in female. This simple and inexpensive tape measurement may play an important role in future diagnosis of obesity and prediction of HTN in resource constrained settings of developing countries.

AbstractObjectiveTo identify the optimal waist:height ratio (WHtR) cut-off point that discriminates cardiometabolic risk factors in Turkish adults.DesignCross-sectional study. Hypertension, dyslipidaemia, diabetes, metabolic syndrome score ≥2 (presence of two or more metabolic syndrome components except for waist circumference) and at least one risk factor (diabetes, hypertension or dyslipidaemia) were categorical outcome variables. Receiver-operating characteristic (ROC) curves were prepared by plotting 1 − specificity on the x-axis and sensitivity on the y-axis. The WHtR value that had the highest Youden index was selected as the optimal cut-off point for each cardiometabolic risk factor (Youden index = sensitivity + specificity − 1).SettingTurkey, 2003.SubjectsAdults (1121 women and 571 men) aged 18 years and over were examined.ResultsAnalysis of ROC coordinate tables showed that the optimal cut-off value ranged between 0·55 and 0·60 and was almost equal between men and women. The sensitivities of the identified cut-offs were between 0·63 and 0·81, the specificities were between 0·42 and 0·71 and the accuracies were between 0·65 and 0·73, for men and women. The cut-off point of 0·59 was the most frequently identified value for discrimination of the studied cardiometabolic risk factors. Subjects classified as having WHtR ≥ 0·59 had significantly higher age and sociodemographic multivariable-adjusted odds ratios for cardiometabolic risk factors than subjects with WHtR < 0·59, except for diabetes in men.ConclusionsWe show that the optimal WHtR cut-off point to discriminate cardiometabolic risk factors is 0·59 in Turkish adults.

Metabolic syndrome (MetS) is a widespread disorder and an important public health challenge. The purpose of this study was to identify the association between salt taste perception, Mediterranean diet and MetS. This cross-sectional study included 2798 subjects from the general population of Dalmatia, Croatia. MetS was determined using the Joint Interim Statement definition, and Mediterranean diet compliance was estimated using Mediterranean Diet Serving Score. Salt taste perception was assessed by threshold and suprathreshold testing (intensity and hedonic perception). Logistic regression was used in the analysis, adjusting for important confounding factors. As many as 44% of subjects had MetS, with elevated waist circumference as the most common component (77%). Higher salt taste sensitivity (lower threshold) was associated with several positive outcomes: lower odds of MetS (OR = 0.69; 95% CI 0.52–0.92), lower odds for elevated waist circumference (0.47; 0.27–0.82), elevated fasting glucose or diabetes (0.65; 0.45–0.94), and reduced HDL cholesterol (0.59; 0.42–0.84), compared to the higher threshold group. Subjects with lower salt taste threshold were more likely to consume more fruit, and less likely to adhere to olive oil and white meat guidelines, but without a difference in the overall Mediterranean diet compliance. Salt taste intensity perception was not associated with any of the investigated outcomes, while salty solution liking was associated with MetS (OR = 1.85, CI 95% 1.02–3.35). This study identified an association between salt taste perception and MetS and gave a new insight into taste perception, nutrition, and possible health outcomes.
