“…Waste pickers who were at risk of mental ill health were more likely to report poor personal health status. This is in agreement with a previous study from India which found a relationship between mental health and SRH [40]. Waste pickers in Guatemala reported fewer visits to clinics due to perceived discrimination by clinic staff which could cause stress and depression [19].…”

Waste pickers are exposed to various environmental health hazards, and self-rated health (SRH) could influence their medical care access. This study investigated the association between illness, clinic visits and SRH, and assessed if SRH can increase clinic visits. A cross-sectional study was conducted. SRH was defined as “very good”, “good”, “fair”, and “poor”. The illnesses were mental health, infectious, and chronic diseases. Medical care access included clinic visits in the previous 12 months. An ordinal logistic regression model was fitted to assess the association. There were 361 participants, 265 (73.41%) were males. Median age was 31 years, (interquartile range (IQR): 27–39). SRH: poor (29.89%), fair (15.92%), good (43.30%) very good (10.89%). Ever smoked (adjusted odds ratio (AOR): 1.72; 95% confidence interval (CI): 1.11–2.66), mental health (AOR: 1.87; 95% CI: 1.22–2.84), chronic (AOR: 2.34; 95% CI:1.47–3.68) and infectious (AOR: 2.07; 95% CI: 1.77–3.63) diseases were significantly associated with increased odds of reporting poor health. Clinic visit was not associated with SRH. From 99 (31%) individuals who rated their health as poor and ill, 40% visited a clinic (p = 0.0606). Acute and chronic illnesses were associated with poor SRH but this did not increase clinic visits. Provision of mobile clinic services at the landfill sites could increase access to medical care.

“…Machado et al [39] reported an association between chronic diseases and poor SRH. A study from India also reported an association between SRH and chronic disease [40]. Chronic diseases like diabetes and hypertension were significantly associated with reporting poor health and were the most prevalent among waste pickers [12,41].…”

“…Studies investigating the association of SRH and physical function at any age in lowand middle-income settings, such as Brazil, are also rare (Pérez-Zepeda et al, 2016;Cullati et al, 2018) and conclusions from studies with high-income populations may not be applicable to lower-income settings. Some authors have noted that individuals from high-income locations, where there are more educational opportunities and health facilities, are in a better position to evaluate their own health status than individuals from low-income settings, where they may be less aware of adverse health conditions affecting them (Sen, 2002;Huisman, Van Lenthe & Mackenbach, 2007).…”

Background Self-rated Health (SRH) is regarded as a simple and valid measure of a person’s health status, given its association to adverse health outcomes, including low physical performance in older populations. However, studies investigating these associations in low- and middle-income settings are scarce, especially for middle-aged populations. Understanding the validity of SRH in relation to objective health measures in low-income populations could assist in decision making about health policy and strategies, especially in under-resourced settings. Objective Assess the relationship between SRH and physical performance measures in middle-aged and older women in a low-income setting of Brazil. Methods This is a cross-sectional study of 571 middle-aged (40–59 years old) and older (60–80 years old) women living in Parnamirim and Santa Cruz in the Northeast region of Brazil. Participants reported their health status and were allocated to the “SRH good” or “SRH poor” groups. The physical performance evaluation included: handgrip strength, one-legged balance with eyes open and closed and chair stand test. The relationship between SRH and physical performance for middle-aged and older women was assessed by quantile regression (modeling medians) adjusted for potential confounders (age, socioeconomic variables, body mass index, menopause status, age at first birth, parity, chronic conditions and physical activity). Results Middle-aged women from the “SRH good” group presented better physical performance with 1.75 kgf stronger handgrip strength (95% CI [0.47–3.02]; p = 0.004), 1.31 s longer balance with eyes closed ([0.00–2.61]; p = 0.030), and they were 0.56 s faster in the chair stand test ([0.18–0.94]; p = 0.009) than those who reported “SRH poor”. No association was found for balance with eyes open. For older women, there was no evidence of associations between physical performance and SRH. Conclusion This study showed that SRH is significantly associated with objective measures of physical performance in a sample of low-income middle-aged women. SRH can be an important tool to indicate the need for further evaluation of physical performance among middle-aged women and can be particularly useful for low-income communities.

“…Second, the study has been conducted in one single country, Switzerland, thus its generalisability is subject to caution. However, studies have suggested construct validity of SRH was similar across very different countries [2]. Third, almost all SRH's covariates, be they health factors, health behaviours, health problems, demographic characteristics, socioeconomic status, etc., were significantly different across waves.…”

Purpose The self-rated health (SRH) item is frequently used in health surveys but variations of its form (wording, response options) may hinder comparisons between versions over time or across surveys. The objectives were to determine (a) whether three SRH forms are equivalent, (b) the form with the best construct validity and (c) the best coding scheme to maximize equivalence across forms. Methods We used data from 58,023 respondents of the Swiss Health Survey. Three SRH forms were used. Response options varied across forms and we explored four coding schemes (two considering SRH as continuous, two as dichotomous). Construct validity of the SRH was assessed using 34 health predictors to estimate the explained variance. Results Distributions of response options were similar across SRH forms, except for the "good" and "very good" options ("good" in form 1: 58.6%, form 2: 65.0% and form 3: 44.1%). Explained variances differed across SRH forms, with form 3 providing the best overall explained variance, regardless of coding schemes. The linear coding scheme maximised the equivalence across SRH forms. Conclusion The three SRH forms were not equivalent in terms of construct validity. Studies examining the evolution of SRH over time with surveys using different forms should use the linear coding scheme to maximise equivalence between SRH forms.
