Thirty eight, chronic, perennial asthmatic children were prospectively examined every six months for a mean 8.9 years to clarify the relation between clinical asthma and puberty. Improvement in the disease occurred independent of puberty but the rate of improvement was appreciably greater during puberty. This led to speculation that improvement in childhood asthma could be associated with an im...
BACKGROUND Cross-sectional studies suggested that allergy prevalence in childhood is higher in boys compared to girls, but it remains unclear whether this inequality changes after puberty. We examined the sex-specific prevalence of asthma and rhinitis as single and as multimorbid diseases before and after puberty onset in longitudinal cohort data. METHODS In six European population-based birt...
BACKGROUND Precocious puberty, as early physical development and low final height might lead to psychosocial problems. OBJECTIVE To evaluate etiology and clinical feature of precocious puberty in a cohort of Iranian children. MATERIALS AND METHODS In this case-series study, 44 girls and 8 boys with precocious puberty referred to Endocrine Reserch Centre (Firouzgar), Institute of Endocrinolo...
Little is known about rates and predictors of remission of childhood asthma after the onset of puberty. We used data collected at ages 6, 8, 11, 13, and 16 years from the Tucson Children's Respiratory Study, a population-based birth cohort. The onset of puberty was defined as the age of appearance of the first pubertal signs as reported by parents. Information on wheezing both before and after ...
Puberty is a fascinating developmental phase that involves the attainment of reproductive capacity and the completion of sexual and somatic maturation. As a life-changing event, puberty onset is precisely controlled by interconnected regulatory pathways that are sensitive to numerous endogenous signals and environmental cues. The mechanisms of normal puberty and its potential deviations have be...
Puberty is a critical risk period for binge eating and eating disorders characterized by binge eating. Previous research focused almost entirely on psychosocial risk factors during puberty to the relative exclusion of biological influences. The current study addressed this gap by examining the emergence of binge eating during puberty in a rat model. We predicted that there would be minimal diff...
Precocious puberty can cause several adverse effects on final growth and social behavior in girls. Recently studies showed that low serum vitamin D levels might be associated with precocious puberty. The aim of this research was to investigate the association between serum vitamin D levels and central precocious puberty in girls. Girls with central precocious puberty under the age of 8 we...
A transient increase in insulin resistance (IR) is a component of puberty. We investigated the impact of body composition and adipokines on IR during puberty in Chinese children. This study included 3223 schoolchildren aged 6-18 years. IR was calculated using homeostasis model assessment (HOMA-IR). We revealed that body mass index (BMI) and waist circumference increased gradually during puberty...
Postweaning growth and puberty traits were studied in 965 heifers produced by mating Hereford and Angus cows to Hereford, Angus, Jersey, South Devon, Limousin, Charolais and Simmental sires. Estrus was checked twice daily from 250 to either 480 or 510 days of age and age and weight at puberty were evaluated. Puberty was defined as date of first standing estrus. Charolais, Simmental and South De...
Timing and rate of sexual maturation and the onset of cigarette and alcohol use among teenage girls.
OBJECTIVE To test the hypothesis that the patterns of pubertal progression, early vs late puberty and fast vs slow, are associated with the age at which girls start to drink alcohol and smoke cigarettes. DESIGN The study included 1463 female students, 10.7 to 18.2 years of age, who were assessed five times during the 2.7-year study. Data regarding pubertal stage, alcohol use, and cigarette us...
