Prevalence of physical inactivity and associated socioeconomic indicators in indigenous Xavante communities in Central Brazil

Effects of the energy balance transition on bone mass and strength

Chronic positive energy balance has surged among societies worldwide due to increasing dietary energy intake and decreasing physical activity, a phenomenon called the energy balance transition. Here, we investigate the effects of this transition on bone mass and strength. We focus on the Indigenous peoples of New Mexico in the United States, a rare case of a group for which data can be compared between individuals living before and after the start of the transition. We show that since the transition began, bone strength in the leg has markedly decreased, even though bone mass has apparently increased. Decreased bone strength, coupled with a high prevalence of obesity, has resulted in many people today having weaker bones that must sustain excessively heavy loads, potentially heightening their risk of a bone fracture. These findings may provide insight into more widespread upward trends in bone fragility and fracture risk among societies undergoing the energy balance transition.

Prevalence and associated factors of physical inactivity among adult diabetes mellitus patients in Felege Hiwot Referral Hospital, Bahir Dar, Northwest Ethiopia

Physical inactivity has been viewed as an emerging public health problem in developing countries including Ethiopia. Diabetes mellitus (DM) is a group metabolic disorder characterized by chronic hyperglycemia resulting from defects in insulin secretion, function, or both. Its prevalence increases with changing lifestyles including physical inactivity across the globe. However, there is limited research, and not yet received attention in Ethiopia. This study aimed to assess the prevalence and associated factors of physical inactivity among adult diabetic patients in Felege Hiwot Referral Hospital, Bahir Dar, Northwest Ethiopia. An institutional-based cross-sectional study design was conducted among 308 participants from February to June 2018 at Felege Hiwot Referral Hospital. A face-to-face interview was conducted using a structured questionnaire by trained data collectors. Participants were selected through a systematic random sampling technique. Physical inactivity was assessed by the international physical activity questionnaire (IPAQ). Collected data were entered in Epi info version 7 and transferred to SPSS version 20 for analysis. A summary of descriptive statistics and multiple binary logistic regression analyses were computed to identify associated factors of physical inactivity among adult diabetic patients. P < 0.05 with 95% CI was considered statistically significant. The overall prevalence of physical inactivity among diabetic patients was 30.5% ( 95% CI: 22.8-33.5%). Gender (AOR = 1.5, 95% CI: 1.1, 3.62), Old age (AOR = 18.17, 95% CI: 22.7, 61.9) Residence (AOR = 4.24, 95% CI: 1,12,16.028), Low self-efficacy (AOR = 20.59, 95% CI: 10.598, 41.608), Poor attitude (AOR = 2.75, 95%CI: 1.44,5.28), and Lack of social support (AOR = 4.22, 95% CI: 1.28,4.07) were found significantly predictor factors of physical inactivity. The prevalence of physical inactivity in this study was high. Being female, old age, dwelling in an urban, having low efficacy, poor attitude, and lack of social support was greater risk factors for being physically inactive. Diabetic education should focus on engagement in physical activity by overcoming barriers to performing physical activity. Government and health professionals should emphasize that evidence-based physical activity important to change their attitudes and require reaching a consensus on social support by their families.

Anemia e níveis de hemoglobina em crianças indígenas Xavante, Brasil Central

RESUMO: Objetivo: Avaliar a prevalência de anemia, os níveis médios de hemoglobina e os principais fatores nutricionais, demográficos e socioeconômicos associados em crianças Xavante, em Mato Grosso, Brasil. Métodos: Realizou-se inquérito em duas comunidades indígenas Xavante na Terra Indígena Pimentel Barbosa visando avaliar todas as crianças com menos de dez anos. Foram coletados dados de concentração de hemoglobina, antropometria e aspectos socioeconômicos/demográficos por meio de avaliação clínica e questionário estruturado. Utilizaram-se os pontos de corte recomendados pela Organização Mundial da Saúde (OMS) para a classificação de anemia. Análises de regressão linear com hemoglobina como desfecho e regressão de Poisson com variância robusta com presença ou não de anemia como desfechos foram realizadas (intervalo de confiança de 95% -IC95%). Resultados: Os menores valores médios de hemoglobina ocorreram nas crianças com menos de dois anos, sem diferença significativa entre os sexos. A anemia atingiu 50,8% das crianças, prevalecendo aquelas com menos de dois anos 2 anos (77,8%). A idade associou-se inversamente à ocorrência de anemia (razão de prevalência - RP - ajustada = 0,60; IC95% 0,38 - 0,95) e os valores médios de hemoglobina aumentaram significativamente conforme o incremento da idade. Os maiores valores de escores z de estatura-para-idade reduziam em 1,8 vez a chance de ter anemia (RP ajustada = 0,59; IC95% 0,34 - 1,00). A presença de outra criança com anemia no domicílio aumentou em 52,9% a probabilidade de ocorrência de anemia (RP ajustada = 1,89; IC95% 1,16 - 3,09). Conclusão: Elevados níveis de anemia nas crianças Xavante sinalizam a disparidade entre esses indígenas e a população brasileira geral. Os resultados sugerem que a anemia é determinada por relações complexas e variáveis entre fatores socioeconômicos, sociodemográficos e biológicos.
