Cognitive consequences of the timing of puberty

2018

In this paper, we use British cohort data to study the degree to which children at different stages of pubertal development at age 11 and 16 differ in their cognitive and behavioral outcomes at age 16 as well as in their completed educational attainment and adult earnings. Controlling for age 7 cognitive skills, region of birth, father's socioeconomic status and parents’ education, we show that boys’ late pubertal development is associated with lower levels of cognitive skills at 16, lower final educational attainment, and lower earnings in adulthood. For girls we find a similar negative relationship between late puberty and cognitive skills, but only imprecise relationships between the tim…

The timing of puberty and gender differences in educational achievement

2017

In this paper, we study the effect of the timing of puberty on educational achievement and examine to what extent the gender differences in the timing of puberty can explain gender differences in achievement. We use British cohort data that combine information on pubertal development with test scores, behavioral outcomes as well as final educational attainment and earnings. Controlling for age 7 cognitive skills and family background, we show that late pubertal development is associated with a slower rate of cognitive skill growth during adolescence. This disadvantage in cognitive development is also reflected in lower levels of educational attainment and earnings for late developed individ…

"Liikun enemmän kesällä, koska on paljon aikaa." : tutkimus yhden yläkoulun oppilaiden liikuntatottumuksista

2016

TIIVISTELMÄ Mäkikokkila, Päivi 2016. ”Liikun enemmän kesällä, koska on paljon aikaa” Tutkimus yhden yläkoulun oppilaiden liikuntatottumuksista. Liikuntakasvatuksen laitos, Jyväskylän yliopisto, pro gradu -tutkielma 56 s, 1 liitesivu. Tässä pro gradu -tutkielmassa olen tutkinut yhden yhtenäiskoulun yläluokkien oppilaiden lii-kuntatottumuksia. Oppilaita pyydettiin kirjoittamaan aiheesta aine ja ne on analysoitu. Oppilai-ta pyydettiin kirjoittamaan muun muassa kuinka paljon he harrastavat liikuntaa päivittäin, mitä liikuntalajeja he harrastavat ja onko heidän liikuntatottumuksissaan eroja kesäloman ja koulun lukuvuoden välillä. Teoriataustana tässä työssä esittelen hieman murrosikää, perehdytä…

Bone growth in pubertal girls : cross-sectional and longitudinal investigation of the association of sex hormones, physical activity, body compositio…

2005

Strong bones are essential to overall health and quality of life. Optimizing peak bone mass during growth is a key strategy in preventing fragility fractures in later life. Understanding the biological process of bone growth and its regulators assumes the greatest importance in realizing this strategy. This study aimed to investigate bone growth in terms of bone size, bone mineral content (BMC) and volumetric mineral density (vBMD) and its relationship with sex hormones, physical activity (PA), body composition and muscle strength in pubertal girls. A total of 258 healthy girls aged 10-13 years were included in the 2-years observational study at baseline. The PA level was assessed using a q…

Psychiatric Problems in Adolescence Mediate the Association Between Childhood Learning Disabilities and Later Well-Being

2021

This follow-up study investigated the associations of childhood learning disabilities (LDs) with adult-age anxiety, depression, and unemployment. Psychosocial problems in childhood and psychiatric diagnoses and lack of education in adolescence were studied as potential mediators, and gender and mother’s education as potential moderators of these associations. Data on childhood clinical neuropsychological assessments and lifelong register data on individuals with childhood LD (n = 430; 301 [70%] males; 20–39 years of age) and matched controls (n = 2,149) were applied. Mediation analyses were performed using structural equation modeling. Childhood LDs exerted a significant, but relatively sma…

Does Serum 25-Hydroxyvitamin D Influence Muscle Development during Puberty in Girls? - A 7-Year Longitudinal Study

2013

Vitamin D is well known for its regulatory role in calcium and phosphate homeostasis, but its role in muscle mass and strength during growth remains inconclusive. We explored the association of serum 25-hydroxyvitamin D (25(OH)D) with muscle development in girls from 11 to 18-years old. Whole body lean tissue mass (LMWB), appendicular lean mass (aLM), muscle cross-sectional area at the lower leg (mCSA), maximal voluntary contraction of elbow flexors (MVC elbow) and knee extensors (MVC knee) were assessed in 217 girls aged 10-13 years (at baseline), 215 in 2-year and 226 in 7.5-year follow-up. Serum concentration of 25(OH)D and intact parathyroid hormone (PTH) were analyzed retrospectively a…

Actual and Perceived Motor Competence, Cardiorespiratory Fitness, Physical Activity, and Weight Status in Schoolchildren : Latent Profile and Transit…

2022

Engagement in physical activity plays a central role in the prevention and treatment of childhood overweight/obesity. However, some children may lack the skills and confidence to be physically active. This 3-year follow-up study aimed to form profiles based on cardiorespiratory fitness, actual motor competence, perceived motor competence, physical activity, and weight status, and to examine if these profiles remain stable from late childhood to early adolescence. All these variables were annually assessed in 1,162 Finnish schoolchildren (girls = 583 and boys = 564, Mage = 11.27 ± 0.32 years). Latent profile analysis was used to identify profiles and latent transition analysis to examine the…
