For instance, leptin is positively associated with the amount of body fat. Obesity may delay puberty in boys - The Globe and Mail Evidence points to the hormone leptin, which is produced by fat cells, as one of the likely culprits, says Carol Elias, Ph.D., a professor of molecular & integrative physiology and obstetrics & gynecology at the U-M Medical School. Is there a causal relationship between obesity and puberty? In conclusion, based on the available evidence, our systematic review and meta-analysis showed that for girls the associate between overweight/obesity and early puberty is definite or strong whereas for males, such an association is possible, prompting that future studies need to further explore the possible relationship between overweight/obesity and early puberty in boys. Obesity Is Associated with Earlier Pubertal Onset in Boys Obesity speeds up the start of puberty in boys, study finds In boys, overweight and obesity have been reported to have higher,2224 lower24,25 or comparable29 Tanner stages in cross-sectional studies. The process can take up to 4 years.

We will refer to the analysis of these siblings as the sibling-matched analysis. Identification of adipokine clusters related to parameters of fat mass, insulin sensitivity and inflammation. Puberty is second to the prenatal period in rapid growth as the long bones stretch to their final adult size. Subgroup analyses for the association between childhood overweight/obesity and early puberty in boys are shown in Table 6. The Committee for Biomedical Research Ethics in Denmark approved the collection of data in the DNBC ((KF)01471/94). Two authors independently screened studies published in English prior to 10 January 2021, which reported overweight/obesity and early puberty. Factors which have been implicated in the accelerated growth in obese children include increased leptin and insulin levels, adrenal androgens, insulin-like growth factor (IGF)-1, IGF-binding protein-1 and GH-binding proteins. (NHANES, 2021) From 1999 -2000 through 2017 -March 2020, US obesity prevalence increased from 30.5% to 41.9%. Therefore, the objective of this study was to perform a comprehensive meta-analysis regarding the association between childhood overweight/obesity and risk of early puberty in both girls and boys. The growth spurt in boys is the peak of growth during adolescence. One remedy is the Mendelian randomization study design that exploits the random allocation of genes at conception to estimate causal effects by using randomized genetic variants as instruments for the exposure of interest.29 Findings from Mendelian randomization studies support a causal relation between childhood obesity and early menarche in girls.62,63 The sibling-matched design is another option for confounding control. Some factors that lead to earlier puberty in obese children include an increase in multiple hormones, including leptin, insulin, and sex hormones (estrogen and androgens). 2010 Sep;140(3):399-410. doi: 10.1530/REP-10-0119. Meta-analytic pooling of these risk estimates yielded a summary OR of 1.29 (95% CI 0.981.70), with substantial heterogeneity (I2 = 68%, p = 0.01). The present study was approved by the Danish Data Protection Agency (201241-0379 and 201557-0002) and the Steering Committee of the DNBC (201204, 201547 and 201827). Childhood overweight and obesity were associated with earlier puberty in a dose-dependent manner in boys and girls in the cohort analysis. And that's not all. The half-yearly questions on puberty in the Puberty Cohort were identical to the questions on puberty in the 11-year follow-up. Sandhu J, Ben-Shlomo Y, Cole TJ, Holly J, Davey Smith G.. What is the average puberty age? Girls are not the only ones who go through puberty early if they have obesity. before puberty can occur, a critical body weight or fat mass must be achieved. Obesity can accelerate puberty in boys | TipTar Subgroup analyses for the association between childhood overweight/obesity and early puberty in boys. A number of these physical changes are very personal. For 100 years, the Endocrine Society has been at the forefront of hormone science and public health. Heterogeneity in the risk estimates of early puberty was partially explained by study design, sample size, follow-up duration, definitions of early puberty and confounders controlled. In studies with a sample size greater than 2,000, obese children were at higher risk of entering puberty early (OR: 2.15, 95% CI: 1.313.53). 20 Nutrition Through the Lifecycle - Puberty - Adolescence - Maricopa Is obesity associated with early sexual maturation? Careers, Edited by: Dartagnan Pinto Guedes, Universidade Norte do Paran, Brazil, Reviewed by: Tuck Seng Cheng, University of Oxford, United Kingdom; Paul B. Kaplowitz, Children's National Hospital, United States, This article was submitted to Children and Health, a section of the journal Frontiers in Pediatrics, These authors have contributed equally to this work and share first authorship. For these cohort studies, the group age of subjects ranged from 4 months to 11 years, and the follow-up time ranged between 3 and 18 years. Sibling comparison designs bias from non-shared confounders and measurement error. Children eligible for this study were live-born singletons born 19962003, whose mothers participated in the first interview in the DNBC (n=86820). Results showed that childhood overweight/obesity were associated with a significantly higher risk of early puberty in girls [odds ratio (OR): 2.22, 95% CI: 1.652.99]. Any disagreements between the two reviewers will be resolved through discussion or consultation with a third reviewer. Putative Effects of Obesity on Linear Growth and Puberty. Begg's test did not show a potential publication bias (z = 0.49, p = 0.624). Press Releases, Policy Letters and more For 100 years, the Endocrine Society has been at the forefront of hormone science and public health. Then, a set of more rigorous selection criteria was used in the screening of the selected studies. 2020 Jun; 49(3): 834844. After subgroup analyses, the variables including study design [test for subgroup differences (TSD): 2= 7.56, p = 0.006], sample size (TSD: 2= 37.64, p < 0.001), follow-up duration (TSD: 2= 5.21, p = 0.02), definition of early puberty (TSD: 2= 49.26, p < 0.001), and confounders controlled (TSD: 2= 8.09, p = 0.004) were shown to be associated with the between-study heterogeneity. Higgins JP, Thompson SG, Deeks JJ, Altman DG. We aimed to investigate the relationship between precocious puberty and obesity as well as central obesity. Systematic Review Registration The median quality score of the included studies was eight. Obesity: According to 2000 growth charts from the Centers for Disease Control and Prevention, Earlier developers were girls who fulfilled at least two of the following three criteria: (1) highest tertile for estradiol, (2) tanner stage three for breast development; and (3) highest tertile for the PDS, Obesity: CDC cut-point for the 85th percentile of BMI (17.626 kg/m2), Maternal age at pregnancy, menarche, pre-pregnancy weight and BMI, height, pregnancy weight gain, prenatal tobacco smoke exposure, education, race/ethnicity and birth size, Obesity:BMI 95th percentile Overweight: >85th BMI <95th percentile at age 11.5, Tanner two development by ages 9.5 and 10.5 years, Obesity: The health-related criterion ( 30 % body fat), Obesity: The percentage of body fat using skinfold thickness: 25%, Breast stage II stage earlier than the median age(9.2 years)for that stage in China, Matched by height, school grade, Tanner stage, family economic status, Obesity: WHO Child Growth Standards BMI 2, Under 8 years for Tanner stage two or above for breast (B2) or pubic hair development (PH2), 10 years for menstruation in girls, and under 9 years for Tanner stage two or above for pubic hair or testicle development (T2) (testicular volume, TV 4 mL) in boys, Obesity/overweight: Chinese Working Group on Obesity, Quartiles of the decimal age of each Tanner stage (>P, Region, age, whether the only child, family economic status, parents' educational level. will also be available for a limited time. Our goal was to identify the genes that were differentially expressed in these two brain areas that could provide some clues about the molecular mechanisms associated with pubertal onset and obesity-induced early puberty, Elias says. Therefore, the results of this study should be extended with caution. Parent AS, Teilmann G, Juul A, Skakkebaek NE, Toppari J, Bourguignon JP.. Future research is needed to confirm the association between childhood overweight/obesity and early puberty in boys based on larger sample size. A few studies found puberty is delayed in obese males - possibly because of excess estrogen in the body. Girls grow 2-8 inches taller, while boys grow 4-12 inches taller. In the cohort analysis, mothers of obese children were more likely to be lower educated, to be smokers, to have higher pre-pregnancy BMI, to have earlier age at menarche and to have higher parity than mothers of normal-weight children (Table1; Supplementary Tables 1 and 2, available as Supplementary data at IJE online). Finally, more recent studies were contained, which makes our results more reliable to present practices. Is obesity associated with early sexual maturation? For girls, puberty can begin as early as eight years old, with most instances of early puberty linked to childhood obesity. Xu YY, Sun L, Guo X, Zhang J, Lou XM, Wang H, et al.. Children with high muscle mass, such as tall and athletic boys, are incorrectly classified as overweight/obesity based on their BMI, which can lead to false link between overweight/obesity in childhood and early puberty (38). Before In the sibling-matched analysis, the patterns were similar for the 1700 brothers and sisters (Supplementary Table 3, available as Supplementary data at IJE online). Overweight/obesity in childhood is a global public health problem that is prevalent in both developing and developed countries (1, 2). However, our data were compatible with the normal distribution. The higher prevalence of obesity among males compared to females in some Arab countries may be related to the difference in timing of puberty, muscular tissue, and dietary habits between. The 5 Stages of Puberty in Boys - Verywell Family Results: The prevalence of general obesity and central obesity among boys was higher than that in girls.

Will obesity affect puberty? - scottick.firesidegrillandbar.com Obesity and male infertility: Mechanisms and management Puberty is second to the prenatal period in terms of rapid growth as the long bones stretch to their final, adult size. More specifically, among children aged 5 or 6, those with obesity were 2.7 times more likely to start puberty early, and those with excess abdominal fat were more likely to reach puberty before the age of 9. Male Obesity and Reproductive Health | IntechOpen Buyken AE, Karaolis-Danckert N, Remer T.. Association of prepubertal body composition in healthy girls and boys with the timing of early and late pubertal markers. To increase the statistical power, these children were sampled according to 12 different prenatal exposures, hypothesized to be causes of earlier pubertal timing, as well as a random sample of 8000 children.38 From August 2012, these 22439 children were invited half-yearly to provide information on pubertal development through web-based questionnaires, from the age of 11.5years until 18years or full maturity (defined as Tanner stage 5 for pubic hair and genital development in boys and Tanner stage 5 for pubic hair and breast development in girls). Of these, 3,409 articles were left after eliminating the duplicate publication, 3,316 articles were excluded after screening the title and abstracts, and 83 of them were excluded after screening the full text. Slowing down childhood obesity and early puberty with exercise and nutrition. Supposing obesity does cause delayed puberty in males, are there implications for individual patients? In addition, the common view is that early puberty is a complex phenomenon caused by many environmental and genetic factors, as well as interactions among these (39). Overweight white boys began the first stage of puberty at an average age of 9.3 years old, versus beginning at 10 years old in boys of normal weight. independently. Mericqs team found that the prevalence of total obesity increased with age, from 22 percent of boys ages 6 to 7 years to 28.6 percent at 11.4 years, the average age at onset of puberty for this group. Senior Communications Manager, Public Relations In addition, a significantly higher elevation in the risk of early puberty related to childhood overweight/obesity was found in studies with none of the confounders controlled (OR: 4.87, 95% CI: 2.0811.39; p = 0.001) when compared with studies that had one or more confounders controlled (OR: 1.38, 95% CI: 1.151.65; p < 0.001). Obesity and Early Puberty: What's the Risk? - WebMD Compared with previous the meta-analysis, our study is more comprehensive since we assessed the association between childhood overweight/obesity and risk of early puberty in both girls and boys. Among all studies included, four studies evaluated the association of childhood overweigh/obesity with early puberty in both boys and girls (19, 2729), five studies only evaluated that in girls (20, 25, 26, 30, 31), and one study only evaluated that in boys (13).

Early puberty might increase the risk of behavior problems and in boys could be related to a higher incidence of testicular cancer in adulthood, Mericq said. When combining the estimates, the pubertal milestones were attained 5.1months earlier in boys and 7.8months earlier in girls per 5kg/m2 higher childhood BMI (Table2). Secondly, case-control studies are prone to recall bias. It should be noted that overweight/obese children were at greater risk of early puberty when the study sample size was greater than 2000 or the follow-up duration was longer than 8 years. Cohort analysis: monthly difference in timing of puberty across childhood weight groups and per 5kg/m2 BMI. For central obesity, which is a more reliable indicator of increased fat mass, the risk was 6.4 times higher. Reference lists of all reviews related to the topic and other included studies were manually searched for additional probably eligible studies. Out of the 10 included studies, seven studies have controlled for one or more confounders, such as parental education, family income, and urban or rural. Higher childhood body mass index was associated with earlier puberty even after adjustment for unobserved time-stabled confounders shared within families in a sibling-matched analysis of sisters. Almost all studies defined early puberty by menarche age, while Chen et al. This sequence conforms to the law of natural development of causality, so it has a strong ability to test the etiology hypothesis. 8600 Rockville Pike Compared to studies with a cohort design (OR: 1.24), subgroup analyses showed that the risk of early puberty related to childhood overweight/obesity was significantly higher in case-control studies (OR: 4.80). Sibling-matched analysis: monthly difference in timing of puberty per 5kg/m2 higher BMI. Furthermore, through subgroup analysis, we found that individuals who were overweight in childhood (OR = 4.67) had a higher risk of early puberty than those who were obesity in childhood (OR = 2.22), which is consistent with the results of a cohort and sibling-matched analyses (i.e., the timing of puberty advances for overweight girls and obese girls was 5.5 months and 5.2 months, respectively) (32). Li WY, Liu Q, Deng X, Chen YW, Liu SD, Story M.. Association between obesity and puberty timing: a systematic review and meta-analysis. Boys -- like girls -- hitting puberty earlier | CNN The following data were extracted: first author, year of publication, study period, geographic region, gender, study design, length of follow-up, and age of enrolment (for cohort studies only), sample size, definition of overweight/obesity, definition of early puberty, and adjustments and matches made. government site.

It was often difficult to determine the time sequence of exposure and outcome, so its causal verification ability was weak. Childhood obesity can be addressed with exercise and nutrition. Qualitative analysis identified that boys with high BMI trajectories had a greater risk of early puberty than boys with low BMI trajectories (13). Boys to Men: Race, Weight, and Timing of Puberty Overweight and Obesity Delay Puberty in Boys Evidence points to the hormone leptin, which is produced by fat cells, as one of the likely culprits, says, Elias and her team have published a new study in the journal, How Stem Cells Grow into Structures That Could Aid Understanding of Infertility, New Insights on Sperm Production Lay Groundwork for Solving Male Infertility, Induced Pluripotent Stem Cells Harnessed to Reliably Create Embryo-like Structures. All claims expressed in this article are solely those of the authors and do not necessarily represent those of their affiliated organizations, or those of the publisher, the editors and the reviewers. The ORs for the association reported by included studies ranged from 1.04 to 2.15. Early growth predicts timing of puberty in boys: results of a 14-year nutrition and growth study. Endocrine Society is a global community of physicians and scientists dedicated to accelerating scientific breakthroughs and improving patient health and well being. Growth Spurts in Boys. Adjusted mean age at attaining the pubertal milestones as spline functions of childhood BMI (body mass index). For people assigned male at birth, puberty begins at age 11 on average, although starting as early as age 9 or as late as age 14 is still considered normal. Data were compatible with these assumptions (data not shown). Obesity and overweight - World Health Organization Both areas lie in the hypothalamus at the base of the brain where the capillaries are relatively opened, allowing circulating molecules to flow easily, increasing the communication between the peripheral organs and the brain explains Elias, who was recently elected as a 2020 fellow of the American Association for the Advancement of Science. Cohort analysis: monthly difference in timing of puberty across childhood weight groups and per 5kg/m, Sibling-matched analysis: monthly difference in timing of puberty per 5kg/m. Obesity and sex steroid changes across puberty: evidence for marked hyperandrogenemia in pre- and early pubertal obese girls, Birth weight, early life weight gain and age at menarche: a systematic review of longitudinal studies, Link between body fat and the timing of puberty, Effects of obesity on human sexual development. Therefore, updating the extent of the association of childhood overweight/obesity with risk of early puberty in girls is necessary, which would help to add important data to the knowledge base. In addition, studies have shown that childhood overweight/obesity may also have adverse effect on the process of puberty (710). Central obesity also increased in that timeframe, from 11.8 percent to 17.4 percent. This may bias the estimates if the assumption of normally distributed residuals is violated. It's an intensive three years! Accessibility sharing sensitive information, make sure youre on a federal Sensitivity analysis were performed by repeating the meta-analysis after the exclusion of each included study; results showed that exclusion of any single study did not materially alter the risk estimate of early puberty in girls (ORs ranged between 1.72 and 2.64; see Table 3). Overweight boys tend to start puberty at a later age than their less-heavy peers, according to one of the first studies to chart the effects of childhood obesity on male sexual development.. Finally, as height and weight were only measured when the child was aged 7years, we were unable to determine the age at the adiposity rebound, which is the onset of the second rise in the BMI curve usually around 5 to 7years.57 The age at the adiposity rebound is influenced by pre- and postnatal nutrition.57 An early adiposity rebound is associated with a low BMI before the rebound, but with high BMI after the rebound, and is a strong predictor of childhood and adult obesity,57 insulin resistance58 and possibly also cardiovascular diseases.59 This is similar to the trajectory of health and disease observed for boys and girls with early puberty.8 However, given the data, we were unable to disentangle the influence of the age at the adiposity rebound on the association between childhood obesity and timing of puberty. Aksglaede L, Juul A, Olsen LW, Sorensen TI.. Age at puberty and the emerging obesity epidemic. As far as we know, this study is the most up-to-date and comprehensive meta-analysis evaluating the relationship between childhood overweight/obesity and early puberty in both boys and girls, which can supply helpful information to both parents and primary health care providers, and help to guide relevant policy and advocacy efforts.

Preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) 2015: elaboration and explanation. When utilizing the data among the 346 boys who had complete data, those who arrived at any given maturation stage at a younger age had lower BMI (p < 0.001) and lower adiposity (p < 0.01). Our findings showed that for girls the associate between overweight/obesity and early puberty is definite or strong whereas for males, such an association is possible, prompting that future studies need to further explore the possible relationship between overweight/obesity and early puberty in boys. Flow chart of children included in the cohort analysis and the sibling-matched analysis. The relation between obesity and male pubertal timing is an ongoing topic of debate ().In contrast to consistent reports of a strong negative association of body mass index (BMI) with female puberty timing across the entire BMI spectrum, conflicting reports concerning the association of BMI with male puberty timing exist.
