The New WHO Cut-off Point for Defining High-altitude Anemia may be Inadequate
These findings suggest that altitude-adjusted Hb cutoffs may overestimate anemia prevalence and lead to misclassification of IDA in high-altitude pediatric populations
Association between iron supplementation and the presence of diarrhoea in Peruvian children aged 6–59 months
Introduction: According to the WHO, anaemia is a severe public health problem when the prevalence is ≥ 40 %. In 2019, in Peru, 40·1 % of children (aged 6 to 35 months) are diagnosed as anaemic. This is a concern since, despite the efforts of the governments to reduce the prevalence, the problem has stagnated since 2011. The treatment applied to deal with anaemia is Fe supplementation. Although Fe is essential for cell function, an excess can prod…
Association between air pollution in Lima and the high incidence of Covid-19
After adjusting for age, sex and number of food markets, the higher rates of COVID-19 in Metropolitan Lima are attributable to the increased PM 2.5 exposure in the previous years, among other reasons. Reduction in air pollution from a long-term perspective and social distancing are needed to prevent the spread of virus outbreaks

Necesidades de investigación para el diagnóstico de anemia en poblaciones de altura
Iron deficiency and overload are risk factors for numerous poor health outcomes, and thus the maintenance of iron homeostasis is vital. Considering that hemoglobin contains 70% of the total iron in the body, the World Health Organization (WHO) recommends the measurement of iron levels to calculate the rate of iron deficiency anemia (IDA), although WHO recognizes that IDA is not the only cause of anemia. As hemoglobin increases with altitude, WHO …

Hemoglobina y testosterona
The different types of response mechanisms that the organism uses when exposed to hypoxia include accommodation, acclimatization and adaptation. Accommodation is the initial response to acute exposure to high altitude hypoxia and is characterized by an increase in ventilation and heart rate. Acclimatization is observed in individuals temporarily exposed to high altitude, and to some extent, it enables them to tolerate the high altitudes. In this …

Prevalencia de anemia en gestantes, Hospital Regional de Pucallpa, Perú
Population based health surveys in Peru show that the general fertility rates, proportion of pregnant adolescents, and maternal and child morbidity are higher in the jungle regions than in other parts of the country. Endemic intestinal parasitic diseases increase the risk of anemia in pregnant women already suffering from iron, folic acid, and other nutritional deficiencies. This is the most common complication of pregnancy in many Latin American…
