- Sensibility and specificity analysis for waist to height ratio, body mass index and waist circumference as a screening criterion for metabolic syndrome in an adult North East Portuguese populationPublication . Teixeira, José Eduardo; Bragada, José A.; Bragada, João P.; Coelho, Joana C.M.M.; Pinto, Isabel; Reis, Luís P.; Saldanha, Laissa de Sousa; Duarte, Carlos Manuel Teixeira; Magalhães, PedroObesity is a central component of Metabolic Syndrome (MetS) and a major public health concern. A harmonizing MetS definition was developed to aggregate the different criteria used by the umbrella organizations, however there is still controversy over the most sensitive and specific parameter to characterize each MetS component
- Overweight, central obesity and abdominal obesity in middle-age adults in an inland region of Northeast Portuguese: a pilot studyPublication . Teixeira, José Eduardo; Bragada, José A.; Bragada, João P.; Coelho, Joana C.M.M.; Pinto, Isabel; Reis, Luís P.; Magalhães, PedroThe prevalence of central and abdominal obesity has been increasing over last decades in developed countries. As well, the high prevalence of obesity in Portugal has already been documented, however it is need to better understand the prevalence in each region of the country. Thus, the aim of this study was to evaluate the prevalence of the overweight, central obesity and abdominal obesity in middle-age in an inland region of Northeast Portuguese. Methods: A descriptive and cross-sectional community sample was collected from two Portuguese primary health care centres between January 2019 and December 2020. A total of 673 individuals aged 40–65 years were included for analysis, among which 400 women (53.34 ± 7.33 years) and 273 men (53.01 ± 7.20 years). Prevalence of overweight, central obesity and abdominal obesity were analysed across sexes using body mass index and waist circumference. Categorical variables were expressed by counts and proportions with a 95% confidence interval (CI). Chi-squared test or fisher exact test were applied whenever appropriate. To compare continuous variables independent sample t-test or Mann-Whitney U test were used. Statistical significance was set at p < 0.05. Results: The prevalence of overweight, central obesity and abdominal obesity in this cross-sectorial sample were 41.01%, 30.61% and 67.20%, respectively. Significant differences among men and women were found for abdominal obesity (p < 0.001). Women presented a higher prevalence of abdominal obesity (67.5%). Men have higher prevalence of overweight (48.72%) and central obesity (31.14%) than women (35.75% and 30.25%, respectively). However, differences were not statistically significant between sexes for overweight and central obesity (p ≥ 0.05). Conclusion: A higher prevalence of overweight, central obesity and abdominal obesity was reported for middle- age adults in this inland region of Northeast Portuguese. Our data suggest a higher prevalence of all three clinical conditions, comparing previous Portuguese epidemiological studies. Current report provides the study pilot for a more detailed epidemiological research. Also, preliminary findings emphasise the importance of implementing physical activity programmes and promoting healthy lifestyles to tackling this growing public health problem.
- Sensibility and specificity analysis for waist-to-height ratio, body mass index and waist circumference as a screening criterion for metabolic syndrome in an adult North-East Portuguese populationPublication . Teixeira, José Eduardo; Bragada, José A.; Bragada, João P.; Coelho, Joana C.M.M.; Pinto, Isabel; Reis, Luís P.; Saldanha, Laissa de Sousa; Duarte, Carlos Manuel Teixeira; Magalhães, PedroObesity is a central component of Metabolic Syndrome (MetS) and a major public health concern. A harmonizing MetS definition was developed to aggregate the different criteria used by the umbrella organizations, however there is still controversy over the most sensitive and specific parameter to characterize each MetS component. The aim of this study was to compare the sensibility and specificity for waist-toheight ratio (WHtR), body mass index (BMI) and waist circumference (WC) to discriminate subjects with and without MetS in an adult North-East Portuguese population. Methods: A cross-sectional retrospective analysis was conducted between January 2019 and December 2020 from patients’ clinical records of two primary health care centers in a North-East Portuguese region. A total of 6570 individuals aged 18–102 years were included for analysis, among which 3865 women (57.37±18.67 years) and 2705 men (59.97±16.76 years). MetS was defined according to HARM2009 statement set by Alberti et al. (2009). Standardized cut-off points were used to measure WHtR (≥0.5), BMI (≥30 kg/m2) and WC (>88 cm in women and >102 cm in men). A binary logistic regression was performed for the areas under receiver operating characteristic curves (AUC) and adjusted odd ratios (OR) with a 95% confidence interval (CI). Results: MetS was present in 3,581 (54.51%) subjects, where 1,914 (49,52%) were women and 1,667 (61.63%) men. AUC demonstrated that WHtR was significantly more powerful than WC and BMI (p<0.05) for screening MetS (AUCWHtR = 0.785, 95% CI: 0.774–0.796; AUCWC = 0.768, 95% CI: 0.757–0.779; AUCBMI = 0.751, 95% CI: 0.703–0.796). Men are 1.53 (95% CI: 1.37–1.72, p<0.001) times more likely of having MetS compared to women. Also, the discriminative power of the three criteria for predicting MetS is higher in men (AUCWHtR = 0.795, 95% CI: 0.778–0.812; AUCWC = 0.783, 95% CI: 0.766–0.801; AUCBMI = 0.740, 95% CI: 0.722–0.759) than women (AUCWHtR = 0.782, 95% CI: 0.768–0.797; AUCWC = 0.760, 95% CI: 0.744–0.775; AUCBMI = 0.699, 95% CI: 0.683–0.716). However, WHtR is still the most powerfull screening criterion for MetS in both sexes. Conclusion: Adjusting individual’s waist circumference to height revealed a greater sensitivity and specificity for MetS screening than isolated WC and BMI. Current research suggests that WHtR is as a better predictor for MetS, specifically in its obesity component.
