HbA^sub 1c^ levels in schoolchildren with type 1 diabetes are seasonally variable and dependent on weather conditions

We evaluated seasonal HbA^sub 1c^ changes in children with type 1 diabetes and its relation with measures of weather conditions. HbA^sub 1c^ changes over more than 3 years were evaluated in type 1 diabetic patients who were younger than 18 years and had diabetes duration of more than 12 months, and...

Description
Summary:We evaluated seasonal HbA^sub 1c^ changes in children with type 1 diabetes and its relation with measures of weather conditions. HbA^sub 1c^ changes over more than 3 years were evaluated in type 1 diabetic patients who were younger than 18 years and had diabetes duration of more than 12 months, and correlated with measures of weather conditions (ambient temperature, hours of sunshine and solar irradiance). After comparison of autocorrelation patterns, patterns of metabolic control and meteorological data were evaluated using Spearman rank correlation. A total of 3,935 HbA^sub 1c^ measurements in 589 school (≥7 years) and 88 preschool (
