“…They concluded that age and seasonality have an impact on mean values for hematological parameter intervals in the first five years of life (Okebe et al, 2016). Also, in a cross-sectional study of 120 school-aged children and teens, the hematocrit was found to reduce significantly during the rainy season while red cell series and blood iron homeostasis had seasonal variation (Rodrigues, Ignotti, & Hacon, 2017). Moreover, in a study of 27,478 children aged 7-17, white blood cell counts were statistically significantly higher in the winter and spring than in the summer and autumn (p ≤ 0.05).…”

BACKGROUND & OBJECTIVES: Premature newborns’ bilirubin conjugation and excretion mechanisms are undeveloped. Seasonal changes and other variables affect the severity of newborns’ physiological jaundice. This study examined blood indices, bilirubin levels, and birth season in neonates in the southern Gaza Strip of Palestine. METHODS: A cross-sectional study of 366 neonates aged one to 14 days was conducted in Medical Nasser Complex-Southern Gaza, Palestine.The newborns were divided into four groups based on season of birth: spring (n=72), winter (n=96), autumn (n=103) and summer (n=95). Blood samples were collected in plain vacutainers for assaying bilirubin profile and complete blood count. Bilirubin and complete blood count were assayed by commercial kits. SPSS software was used for data analysis. RESULTS: Indirect and total bilirubin showed significant seasonal variations, whereas direct did not. Spring and winter have increased indirect and total bilirubin. Seasonal hemoglobin levels varied significantly. Red blood cells, hemoglobin, and hematocrit positively correlated with total and indirect bilirubins. CONCLUSION: Spring and winter births exhibited higher indirect and total bilirubin in the first two weeks. The birth season appears to affect newborn jaundice. Short sunshine duration may increase neonatal hyperbilirubinemia risk.

“…Remarkably, the iron status of the adolescent girls in this study differed with the season, with the highest prevalence of ID observed in the wet season in the three saline regions. A Brazilian study showed the mean serum ferritin concentrations of riverine populations were higher in the dry season than in the rainy season 52 . One reason contributing to the increasing levels of ID during the wet season may be the mixing of surface water and groundwater during the rainy season, which lowers the overall iron content of the mixed water 53 .…”

Inadequate intake of both macro and micronutrients is the major determinant of micronutrient deficiencies in adolescent girls. This study assessed multiple micronutrient status including vitamin D, iron, vitamin A, and urinary iodine concentration among adolescent girls through two seasonal cross-sectional surveys conducted during dry and wet seasons. Mixed-effects linear and logistic regression analysis were conducted to assess associations between micronutrient status, salinity and seasonality. The mean age of the girls was 14 years. Vitamin (OH)D insufficiency was significantly higher in freshwater areas in wet season compared to dry season (wet season: 58% and dry season: 30%, P < 0.001). In wet season, risk of vitamin (OH)D insufficiency was three times higher compared to dry season (AOR: 3.03, 95% CI 1.71, 5.37, P < 0.001). The odds of vitamin (OH)D insufficiency was 11 times higher in fresh water areas compared to high saline areas (AOR: 11.51, 95% CI 3.40, 38.93, P < 0.001). The girls had higher risk of iron deficiency in wet season. Despite the environment being enriched with micronutrient-contained aquatic food, adolescent girls in coastal areas experience different micronutrient deficiencies. The high prevalence of vitamin (OH)D insufficiency in freshwater locations and seasonal iron deficiency in high saline areas needs attention.

“…No entanto, as frequências de anemia no Brasil apresentam grandes variações dependendo da região estudada (comunidade, cidade e/ou estado), local da coleta (Unidade Básica de Saúde ou em creches/escolas), e a idade do grupo estudado [5][6][7][8][9][10][11][12][13] . Pois, diversos fatores podem influenciar o desfecho estudado.…”

“…Na literatura, os fatores que associam com a anemia estão envolvidos com as características socioeconômicas, maternas, de aleitamento materno, e fatores individuais das crianças [5][6][7][8][9][10][11][12][13] . Podendo destacar a menor renda, o maior número de moradores 5 , maior número de filhos 5,7 , amamentação não exclusiva 12 , menor idade materna 9 , menor idade da criança e o estado nutricional 11,12 .…”

Objetivo: Identificar a prevalência e fatores associados à anemia em crianças menores de cinco anos de creches municipais em Juiz de Fora – MG. Métodos: Estudo transversal com 809 crianças matriculadas em tempo integral. Para determinação da hemoglobina utilizou-se hemoglobinômetro portátil, e 11 g/dL como ponto de corte para o diagnóstico da anemia. Aplicou-se questionário contendo informações socioeconômicas, características maternas, de aleitamento materno, de alimentação complementar, e características individuais da criança. O estado nutricional foi avaliado pelas medidas antropométricas de peso e estatura, na avaliação da alimentação foi utilizado recordatório 24 horas e o registro alimentar. Análise de regressão de logística e seleção hierárquica das variáveis foram usadas para verificar fatores associados. Resultados: A prevalência de anemia foi de 39,2%, a idade materna (β=-0,48, IC95%=0,91-0,99), o número de gestações (β=0,19, IC95%=1,02-1,43), o baixo peso ao nascer (OR=2,51; IC95%=1,12-5,63) e o peso/idade (β=-3,98; IC95%=0,01-0,90) associaram a anemia. Conclusão: A anemia nas creches das regiões estudadas é considerada um problema de saúde pública moderado. As variáveis que associaram a anemia relacionam-se as características maternas e as características individuais das crianças.

Association between weather seasonality and blood parameters in riverine populations of the Brazilian Amazon

Abstract: Hematological parameters of the red cell series and blood iron homeostasis had seasonal variation, which coincided with the dry season in the region, in which an increase in atmospheric pollutants derived from fires is observed.
