Abstract Background The sagittal abdominal diameter (SAD) is more precise than body mass index (BMI) for predicting adverse events in elderly. While physical function and BMI is related, the relationship is uncertain. BMI and gait speed (GS) is related and have a U-shaped distribution. The objective was to examine the relationship between GS and SAD in men and women aged 50 years and older. Methods This was a cross-sectional analysis. Data from the Handan Eye Study (HES), a Chinese prospective longitudinal study with participants randomly selected from the Yongnian county. Usual GS was measured over a 4 meters-track. SAD was categorized by interquartile: <18.0cm; 18.0-19.79cm; 19.8-21.89cm; ≥21.9cm. Unadjusted and adjusted analyses of covariance were performed to estimate the gender-specific means (and 95% CI) of GS (in m/s) according to SAD categories. Results The current analyses were performed in 2852 participants. Mean age was 56.16 years for women and 56.54 years for men. The unadjusted means of GS were 0.995 (95% CI 0.972-1.019) m/s in SAD Q1 participants, 0.991 (95% CI 0.968-1.014) m/s in SAD Q2, 0.986 (95% CI 0.964-1.007) m/s in SAD Q3 and 0.961 (95% CI 0.937-0.985) m/s in SAD Q4 individuals in women. The similar trend presented in men [Q1: 0.993 (95%CI 0.969-1.016) m/s; Q2: 0.980 (95%CI 0.956-1.004); Q3: 0.944 (95%CI 0.918-0.970); Q4: 0.948 (95%CI 0.923-0.973)]. After adjustment for age, the reported trends between GS and SAD in categories were largely confirmed in women, but not in men. Conclusions Age and gender should be considered when we explore the relationship between GS and SAD in elderly.

Seasonality of 25(OH)D deficiency rate is a factor of major clinical and social impact and should be considered when planning for appropriate testing and tailored correction. We present retrospective cross-sectional analysis of over a million 25(OH)D tests performed in two leading Latvian laboratories – Central Laboratory and E.Gulbja Laboratory. Both series of tests demonstrated prominent seasonal variability of 25(OH)D deficiency rate (<20 ng/ml) and critical deficiency rate (<12 ng/ml): the lowest percentage of deficient tests was in August, while a significant peak was found in March-April. This trend was present at all ages and in both genders, variations were pronounced even for a high-latitude country and more prominent for critical deficiency, in younger age groups and in males. Analysis of testing regimens of both laboratories revealed that schedule was not optimal, period of higher testing intensity being far removed from the 25(OH)D deficiency peak.

Abstract Background This is a cross-sectional study to explore the age and gender specific association between obesity and depression in Chinese rural adults. Methods A total of 29,900 eligible participants from the Henan Rural Cohort Study were included. Standard anthropometric measurements were undertaken to obtain data on body mass index (BMI) and waist circumference (WC). The Patient Health Questionnaire-2 (PHQ-2) was utilized to discover depressive symptoms. Logistic regression was performed to explore the association between obesity (independent variable) and depressive symptoms (dependent variable). Results There were 1777 subjects with depressive symptoms, accounting for 5.94%. After multivariable adjustment, compared with normal weight group, the odds ratios (ORs) [95% confidence interval (CI)] for depressive symptoms in underweight, overweight and general obese groups were 1.41 (1.08–1.84), 0.87 (0.78–0.97) and 0.86 (0.74–0.99), respectively. Similarly, the OR (95% CI) of abdominal obesity group was 0.84 (0.76–0.93). Besides, there was linear decreasing trend of WC with depressive symptoms, but not BMI. Moreover, the inverse association between obesity and depressive symptoms was stronger in men and the elderly than that in women and the young. Conclusion Underweight was associated with a higher prevalence of depressive symptoms, which indicated that health care should pay attention to underweight as well as obesity, especially for women and the young. Clinical trial registration The Henan Rural Cohort Study has been registered at Chinese Clinical Trial Register (Registration number: ChiCTR-OOC-15006699). Date of registration: 2015-07-06.

Abstract Background: Childhood obesity and its consequences have reached alarming proportions worldwide and in India. Wrist circumference is emerging as an easily measurable reproducible parameter for screening children at risk of obesity-related morbidities such as hypertension and insulin resistance. The objectives of this study were: (1) to compute age and gender-specific wrist circumference percentiles for 3–18-year-old apparently healthy Indian children and adolescents; (2) to assess the relationship of wrist circumference with measures of obesity and adiposity such as body mass index (BMI), fat percentage and blood pressure (BP) and (3) to suggest age and gender-specific cut-offs for wrist circumference percentile for the risk of hypertension in Indian children and adolescents. Methods: This was a cross-sectional study on samples of 10,199 3–18-year-old children (5703 boys) from randomly selected schools from five major cities in India. Height, weight, waist and wrist circumference and BP were recorded. Body composition was measured using bioelectrical impedance analysis (BIA). Wrist circumference percentiles were computed using the LMS method. Results: The average wrist circumference of boys and girls was 10.4 cm and 10.0 cm at 3 years and increased to 15.1 cm and 13.9 cm, respectively, at 18 years. Compared to their Caucasian counterparts, Indian children’s wrists were smaller. Receiver operating characteristic (ROC) curve analysis derived the 70th percentile of wrist circumference as the cut-off for identifying the risk of hypertension. Conclusions: Contemporary cross-sectional reference percentile curves for wrist circumference for 3–18-year-old Indian children are presented. The 70th percentile of the current study is proposed as the cut-off to screen children for cardiometabolic risk factors such as hypertension.

ABSTRACTThe purpose of this study was to examine whether older age is associated with increasing loneliness in people aged 60 and over. Data came from TamELSA, a population-based prospective longitudinal study in Tampere, Finland. The follow-up time was 20 years. Loneliness was measured by a single question – “Do you feel lonely?“ – with the possible answers often, sometimes, or never. Cross-sectional analysis showed that the percentage of subjects feeling lonely increased toward older age groups, but in a multivariate analysis, only household composition and social participation were independently associated with loneliness. Longitudinal analysis showed that loneliness increased with higher age. Over a 10-year period, loneliness increased most in those who, at baseline, were married and living alone with their spouse. In conclusion, only a minority of older people continuously suffer from loneliness. Loneliness does increase with age, not because of age per se, but because of increasing disability and decreasing social integration.

Abstract Background: Little is known about age and gender specific attitudes to performance enhancing drugs and methods or other characteristics by which attitudes may vary. Methods: Using a population based cross-sectional sample of 1,703 Danish men and women aged 15-60 years, the present study examined age and gender variation in attitudes to performance enhancing drugs and methods. Response rate was 34 %. Information on attitudes was collected by questionnaire. Results: Overall, participants held negative attitudes to drugs and methods enhancing predominantly cognitive abilities enhancing performance drugs and to appearance modifying methods, but were positive to drugs for restoring physical functioning conditions. However, attitudes varied nonlinearly across age. Lenient attitudes peaked at age around 25 and subsequently decreased. Lenient attitudes to use of drugs against common disorders decreased in a linear fashion. No gender differences were observed and attitude did not vary with level of education, self-reported health or weekly hours of physical activity. Conclusion: The present study expands existing knowledge about attitudes toward PEDM with respect to age and gender specific differences. Future studies should take age variations into account, when examining attitudes to PEDM in the general population.
