“…Data regarding the proportion of anemia in men and women and the relationship between anemia and ethnic background have also been described. 3,12 Although females predominated in this study, a higher occurrence of anemia was observed in older men confirming results previously reported 3,10,12–14 but different to two studies performed in different regions of Brazil by Barbosa et al 4 and Sgnaolin et al 5 This study found no association with regard to ethnic background; the ethnic background of patients was to some extent biased due to the subjectivity of the question. This variable was studied according to the definition of each patient without any interference of the health professional who applied the questionnaire.…”

“… 12 On the other hand, data from low and middle-income countries are sparse. Bryce et al 13 surveyed 10,915 people aged 65 years and over in catchment areas in Cuba, Dominican Republic, Puerto Rico, Venezuela and Mexico and found anemia prevalence rates of 19.2%, 37.3%, 32.1%, 9.8% and 9.2% respectively; in all these countries anemia increased with age. In a population-based study performed among 392 free-living elderly in south Brazil, the overall prevalence of anemia was 12.8% and this increased with age.…”

“…As described before, the lack of association for the place of residence, years of schooling, income and anemia suggests that socioeconomic aspects did not play a role in the current sample. 3,12,13 …”

ObjectiveTo demonstrate the proportion of anemia and its association with demographic and clinical characteristics in a representative sample of elderly people from São José dos Campos, São Paulo.MethodsDemographic data and blood samples were collected from 398 over 65-year-old male and female individuals. Anemia was defined as hemoglobin concentration <12 g/dL in women and <13 g/dL in men. Anemic and non-anemic groups were compared using the chi-squared test and a multiple logistic regression model.ResultsThe prevalence of anemia was 18.6% (20.8% in men and 17.6% in women). The percentages of anemia rose significantly across the age groups >75–80, >85–90 and >90–95 years (p-value = 0.0251). There were no significant differences in gender, ethnic background, place of residence, years of schooling, income, comorbidities and use of medications. According to gender, the mean hemoglobin concentration and mean corpuscular volume were 11.5 g/dL (range: 8.4–11.9 g/dL) and 90.7 fL (range: 63.0–111.7 fL) for women and 11.9 g/dL (range: 8.6–12.8 g/dL) and 92.1 fL (range: 59.8–100.1 fL) for men. The great majority of anemia cases were mild with less than 6% having hemoglobin concentrations below 10.9 g/dL. Mean corpuscular volume was lower than 80 fL in six cases (8%), between 80 and 100 fL in 65 cases (88%) and higher than 100 fL in three cases (4%).ConclusionA total of 18.6% of elderly people from São José dos Campos had mild anemia with the majority being normocytic. The percentages of anemia rose as the age increased demonstrating an association between age and anemia.

“…Likewise, a recent population-based study conducted among older adults in Latin America reported lower anemia prevalence rates in Cuba (19.2%) and Venezuela (9.8%). On the contrary, up to 37.3% and 32.1% of older adults in Dominican Republic and Puerto Rico were classified as having anemia, respectively [24]. The present results indicate that the prevalence of anemia in older Ecuadorians is comparable to that recently described among subjects aged 65 years and older in Portugal (21.0%) [25].…”

Objectives. To estimate the prevalence of anemia and its determinants among older adults in Ecuador. Methods. The present study was based on data from the National Survey of Health, Wellbeing, and Aging. Hemoglobin concentrations were adjusted by participants' smoking status and altitude of residence, and anemia was defined according to the World Health Organization criteria (<12 g/dL in women and <13 g/dL in men). Gender-specific logistic regression models were used to examine the association between demographic and health characteristics and anemia. Results. A total of 2,372 subjects with a mean age of 71.8 (SD 8.2) years had their hemoglobin measured, representing an estimated 1.1 million older adults. The crude prevalence of anemia was 20.0% in women and 25.2% in men. However, higher anemia prevalence rates were seen with advancing age among black women and subjects residing in the urban coast. Likewise, certain health conditions such as hypoalbuminemia, cancer in men, chronic kidney disease, iron deficiency, and low grade inflammation were associated with increased odds of having anemia. Conclusions. Anemia is a prevalent condition among older adults in Ecuador. Moreover, further research is needed to examine the association between anemia and adverse health-related outcomes among older Ecuadorians.

“…In addition, we did not find an association between anaemia and functional limitations, unlike a recent study in South America (Bryce et al, 2013). We have no clear explanation for the differences in the association between anaemia and handgrip strength in men and women in our population.…”
