Background. Waist girth and BMI are commonly used as markers of cardiometabolic risk. Accumulating data however suggest that sagittal abdominal diameter (SAD) or “abdominal height” may be a better marker of intra-abdominal adiposity and cardiometabolic risk. We aimed to identify cutoffs for SAD using a cardiometabolic risk score.Design. A population-based cross-sectional study.Methods. In 4032 subjects (1936 men and 2096 women) at age 60, different anthropometric variables (SAD, BMI, waist girth, and waist-to-hip ratio) were measured and cardiometabolic risk score calculated. ROC curves were used to assess cutoffs.Results. Among men SAD showed the strongest correlations to the majority of the individual risk factors; whereas in women SAD was equal to that of waist girth. In the whole sample, the area under the ROC curve was highest for SAD. The optimal SAD cutoff for an elevated cardiometabolic risk score in men was∼22 cm (95%CI; 21.6 to 22.8) and in women∼20 cm (95%CI; 19.4 to 20.8). These cutoffs were similar if the Framingham risk score was used.Conclusions. These cutoffs may be used in research and screening to identify “metabolically obese” men who would benefit from lifestyle and pharmacological interventions. These results need to be verified in younger age groups.

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.

High Frequency Hearing Loss

Hearing loss (≥26 dB threshold in the better ear), as a common chronic condition in humans, is increasingly gaining attention. Relevant research in China is relatively scarce, so we conduct a population-based study to investigate the prevalence of hearing loss among age groups, genders and ears in Zhejiang province, China, from September 2016 to June 2018.Study designPopulation-based cross-sectional studyParticipantsA total of 3754 participants aged 18–98 years and living in Zhejiang province, China.Outcome measuresPure-tone audiometric thresholds were measured at frequencies of 0.125–8 kHz for each subject. All participants were asked to complete a structured questionnaire, in the presence of a healthcare official.ResultsThe prevalence of speech-frequency and high-frequency hearing loss was 27.9% and 42.9%, respectively, in Zhejiang. There were significant differences in auditory thresholds at most frequencies among the age groups, genders (male vs female: 31.6%vs24.1% at speech frequency; 48.9% vs 36.8% at high frequency) and ears. In addition to the common factors affecting both types of hearing loss, a significant correlation was found between personal income and speech-frequency hearing loss (OR=0.69, 95% CI 0.52 to 0.92), and between hyperlipidaemia and high-frequency hearing loss (OR=1.45, 95% CI 1.02 to 2.07).ConclusionThe prevalence of hearing loss was high among people living in Zhejiang, particularly males, and in the left ear. Moreover, hearing thresholds increased with age. Several lifestyle and environment factors, which can be influenced by awareness and education, were significantly associated with hearing loss.

ABSTRACT Background The WHO currently recommends a daily sodium intake of 2 g and has established the goal of a 30% reduction in mean salt intake by 2025. Objective We sought to estimate sodium intake in study participants according to the locations of where they consumed meals and their demographic and socioeconomic characteristics and practices related to salt consumption. Methods A population-based, cross-sectional study was conducted with a sample of 2574 individuals aged ≥10 y who answered the 2015 Campinas-Brazil Nutrition Survey. Mean sodium intake was estimated using a 24-h recall log and associations with the independent variables were tested using generalized regression analysis stratified by age group. Results Sodium intake was higher in male participants as well as adolescents and adults who reported eating ≥1 meal outside the home (6.07% and 7.06% increase, respectively). Per meal, sodium was consumed more outside the home at breakfast, during an afternoon snack, and at dinner among adolescents. No significant differences were found in the analysis by type of meal among the adults and seniors. Conclusions Sodium intake exceeded the WHO recommendation in all age groups analyzed. Having ≥1 meal outside the home was associated with greater sodium intake among adolescents and adults. Measures to regulate the food industry and dietary/nutritional education strategies targeting consumers are important to reducing the sodium intake of the population.

AbstractObjective:To evaluate the role of central adiposity, as evaluated by the measurement of waist circumference (WC), as an independent risk factor for hypertension and type 2 diabetes mellitus in the setting of a developing country.Design:Population-based, cross-sectional study.Setting:A medium-sized town in southern Brazil.Participants:One thousand and ninety-five non-pregnant women, 20 to 69 years old, recruited by cluster random sampling between 1999 and 2000. Their mean WC was 85.3 cm (standard deviation 13.9 cm) and 23.3% (n = 255) were obese (body mass index >30 kg m−2). The prevalence of hypertension and diabetes was 25.6% (n = 280) and 6.2% (n = 68), respectively.Results:The risks of hypertension and diabetes were directly related to WC measurement. Women with WC > 80 cm had increased risk of hypertension (odds ratio (OR) = 6.2, P < 0.001). The association remained significant (OR = 1.04 per cm increase in WC, P = 0.02) after adjusting for confounders. The effect of WC on diabetes was modified by age. The effect was stronger in women younger than 40 years old (OR = 12.7, P = 0.016) than in those over 40 years old (OR = 2.8, P = 0.013). In the multivariate analysis, the odds ratio was 5.7 (P = 0.12) in those under 40 years old and 2.8 (P = 0.008) in older women.Conclusions:Waist circumference is an independent determinant for hypertension and diabetes in women in this population. The stronger association between WC and diabetes in younger women suggests that the validity of this indicator to assess abdominal adiposity is age-specific. Further studies should validate the usefulness of WC measurement in different age groups.

Abstract Background: This study aimed to assess the prevalence, associated factors and awareness of hypertensive retinopathy among an elderly population with hypertension in Nepal Methods: A population-based, cross-sectional study was conducted from 2013 to 2015 in Bhaktapur district, Nepal. The sample size was 2100 subjects age 60 years and above. From this sample, all diagnosed patients with hypertension were analyzed. A detailed history was obtained, and an ocular examination was performed. Blood sugar and blood pressure were measured. Result: Information was complete for 1860 (88.57%) subjects. The age ranged from 60 to 95 years with the mean ± SD age of 69.64±7.31 years. Hypertension was found in 643 subjects (34.61%), of which 224 (12.04%) were newly diagnosed cases. Hypertensive retinopathy was found in 81 cases (12.6%). Grade 1, grade 2, and grade 3 hypertensive retinopathy comprised 53 (65.43%), 19 (23.46%), and 9 (11.11%) cases, respectively. Hypertensive retinopathy was more frequent in the age group 70-79 years (15.23%) compared to other age groups, among males (13.25%), illiterates (13.56%), diabetics (16.49%), and those with body mass index (BMI) ≥25 kg/m2 (14%). However, none of the factors was found to be statistically significant. Among the subjects with hypertension, awareness of hypertension’s effects on the eyes, retina and vision was found in 13.84%, 8.4%, and 11.98% respectively. Conclusion: Prevalence of hypertension, hypertensive retinopathy and associated factors among an elderly population were similar to other countries. Awareness of hypertensive retinopathy was found in only 8.4%. Increased emphasis should be directed toward improving awareness campaigns.

ObjectiveTo estimate the prevalence of childhood epilepsy in Sri Lanka by different age groups (0–5, 6–10 and 11–16 years), sex and ethnicity, and to describe the types and outcomes of epilepsy.Design and patientsA population-based, cross-sectional study was conducted in the district considered to be ethnically most balanced in Sri Lanka. A door-to-door survey was performed in the 0–5 year age group (60 geographically defined areas as clusters; 19 children per cluster), and a school-based survey in the 6–16 year age group (150 classes as clusters; 25 children per cluster). The screened children with epilepsy were reviewed individually for confirmation of the diagnosis of epilepsy, typing of the underlying epilepsy syndrome and assessment of control. The same group of children were re-evaluated 1 year later to reconfirm the syndromic diagnosis and to assess the stability of control of epilepsy.ResultsThe overall prevalence of childhood epilepsy was 5.7 per 10 000 children aged 0–16 years (95% CI: 38 to 87). It was higher with younger ages (73.4 per 10 000 children aged 0–5 years; 55.1 per 10 000 children aged 6–10 years and 50.4 per 10 000 children aged 11–16 years). A male dominance was noted in both age groups. In each age group, the prevalence was highest in children of Sinhalese ethnicity. Symptomatic focal epilepsy was the single most common group of epilepsy in both age groups. Majority of children remained well controlled on medications.ConclusionThe findings indicate a relatively high burden of epilepsy among children in Sri Lanka, however, these were comparable to the burden of disease reported from other countries in the region.
