Sociodemographic features incorporated racial notice-class (white or non-white e.grams. black, brown, reddish, otherwise local), host to home (metropolitan otherwise rural), schooling (0–4, 5–8, 9–11, or ? 12 years), and monthly house earnings for every capita inside tertiles (lower, center, otherwise high). Brand new urban–outlying class is based on the methods used by the latest Brazilian Institute from Geography and Statistics (into the Portuguese, IBGE) inside 2010 population census regarding administrative constraints put down of the regional laws. Within this per municipality’s borders, these local laws and regulations introduce an imaginary line named “metropolitan perimeter”. The census tracts found for the “urban perimeter” was termed metropolitan, whereas the remaining parts is actually designated rural. The other information was gotten owing to a facial-to-deal with interviews in the participant’s house.

Anthropometric parameters

Height was measured in centimeters (cm) using a portable vertical stadiometer (NutriVida®, Brazil) with the participants barefoot with legs and feet parallel, weight distributed on both feet, arms relaxed at the sides, palms facing the body, and head in the Frankfurt horizontal plane. Weight was measured in kilograms (kg) using a portable digital scale (SECA® Pakistansk kvinner for ekteskap, Germany) with participants barefoot. Body mass index (BMI) was calculated as the ratio between weight in kilograms (kg) and height in square meters (m 2 ). BMI cutoff points were based on the World Health Organization recommendation: underweight (< 18.5> 94 cm in men and > 80 cm in women were considered “increased” since they are associated with a higher risk of metabolic complications . All anthropometric variables were measured twice during the home visit by trained interviewers and the mean of the measurements was used in the analyses. Further information can be seen in the handbook on the survey homepage (

Analytical investigation

Additionally, we provided information on the most prevalent chronic diseases diagnosed by a physician in our sample. Secondly, fractional polynomial regression models were fitted to estimate the percentiles (P5, P10, P20, P25, P50, P75, P90, and P95) of HGS by age group and sex. This method provides smooth centile curves and explicit formulae for the percentile estimates. Diagnostic tests were used to evaluate the model fit (normal plot of the Z-scores, Shapiro–Wilk test, and residuals plot). The model was fitted by maximum likelihood, which accounts for non-normal skewness and/or kurtosis in the data . Thirdly, HGS centile curves for men and women were plotted in charts. Finally, unadjusted and adjusted logistic regression models separate for men and women were created to investigate the sociodemographic and anthropometric variables associated with muscle weakness, being estimated the odds ratio (OR) with 95%CI. Variables with p < 0.20>


Figure 1 describes the flow chart of the participants throughout the study. Our analytical sample was composed of 7905 participants aged 50–101 years (63.1 ± 9.1 years): 3162 men (63.2 ± 8.7 years) and 4743 women (63.1 ± 9.4 years). The excluding participants were similar to including participants regarding sex (p = 0.092), schooling (p = 0.813), and monthly household income per capita (p = 0.189) but tended to be older (? 80 years: 11.8% vs. 6.5%, respectively, p < 0.001).

The characteristics of the study users because of the sex is seen for the Table step 1. In both sexes, extremely professionals have been low-light, lived in the fresh new area, got 0–cuatro years of education, and displayed improved hips width. Regarding the Body mass index, fat is the most common classification for men (42.9%), when you are over weight and being obese had nearly equivalent frequencies for ladies (36.9% and you may thirty five.4%, respectively). Regarding persistent sickness, forty two.1% from participants said that have a healthcare medical diagnosis off arterial hypertension, 17.4% off diabetes mellitus, 11.5% out-of osteoporosis, 7.4% out-of cardiovascular system disorder (angina, myocardial infarction, and you can cardiovascular system failure), and you can 5.7% away from breathing ailment (symptoms of asthma and you can persistent obstructive pulmonary condition).
