“…The circadian pattern of BP was classified according to the percentage decline in BP from daytime to nighttime. To keep in line with the guideline published by European Society of Hypertension (ESH) and previous studies of pediatric hypertension, non-dippers were defined as less than 10% reduction in nocturnal SBP or DBP [14,[17][18][19]25]. Isolated nocturnal hypertension (INH) was defined as hypertension during the night with normal daytime BP.…”

“…However, it remains unclear whether more severe obesity in young people is associated with a higher risk of non-dipping patterns. A few previous studies on this topic have generated conflicting results due to either small sample sizes or participants with a wide age range, from kindergarten kids to college students [13,[17][18][19]. In addition, none of the above studies have considered sex differences.…”

Background For adolescents, abnormal dipping patterns in blood pressure (BP) are associated with early-onset organ damage and a higher risk of cardiovascular disorders in adulthood. Obesity is one of the most common reasons for abnormal BP dipping in young people. However, it is unknown whether the severity of obesity is associated with BP dipping status and whether this association is sex-dependent. Methods 499 participants between 12 and 17 years old with overweight or obesity underwent ambulatory blood pressure monitoring (ABPM) between April 2018 and January 2019 in Beijing and Baoding. Participants were grouped by body mass index (BMI) into overweight (BMI 85th–95th percentile), obese (BMI ≥ 95th percentile) and severely obese (BMI ≥ 120% of 95th percentile or ≥ 35 kg/m2) groups. Non-dipping was defined as a < 10% reduction in BP from day to night. The interaction effect between sex and obesity degree was also analyzed. Results 326 boys and 173 girls were included, of whom 130 were overweight, 189 were obese, and 180 were severely obese. Girls with severe obesity had a higher prevalence of non-dipping, but boys showed no significant differences in BP dipping status between obesity categories. In addition, as obesity severity went up, a more evident increase in night-time SBP was observed in girls than in boys. Conclusions Severely obese is associated with a higher prevalence of non-BP dipping patterns in girls than in boys, which suggests that the relationship between the severity of obesity and BP dipping status might be sex-specific.
