We conducted the present meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Statement (21). Children eligible for this study were live-born singletons born 19962003, whose mothers participated in the first interview in the DNBC (n=86820). 2017;88(1):101-110. doi: 10.1159/000455968. The DNBC comprises approximately 100000 children and their mothers. Tanner stage 2 (dashed line), Tanner stage 5 (solid line), voice break (dashed line), first ejaculation (solid line) and menarche (solid line). The behavior of maximum likelihood estimates under nonstandard conditions. 13, 14, 16 - 23, 49 - 51 An explanation for the early onset of puberty in these girls might be found in the secretion of adipokines. A previous meta-analysis published in 2017, including five cohort studies with a total of 1,360 girls, has showed that early puberty was significantly associated with childhood overweight/obesity (RR = 2.44) (18). Selected characteristic of 7 cohort studies of childhood overweight/obesity and early puberty. The Then, a set of more rigorous selection criteria was used in the screening of the selected studies. [Associations between early onset of puberty and obesity types in children: Based on both the cross-sectional study and cohort study]. It's an intensive three years! Identification of modifiable causes of earlier puberty is, therefore, warranted. Its possible that leptin is speeding up the development of these structures in the base of the brain.. 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). For girls, puberty can begin as early as eight years old, with most instances of early puberty linked to childhood obesity. Childhood overweight and obesity were associated with earlier puberty in a dose-dependent manner in boys and girls in the cohort analysis. Euling SY, Herman-Giddens ME, Lee PA. In girls, we found that higher childhood BMI was associated with earlier age at attaining all pubertal milestones, in a dose-dependent manner. The potential relationship between childhood obesity and earlier puberty onset has major public health implications. Secondly, substantial heterogeneity was found in this meta-analysis. For the cohort study, information on childhood BMI obtained from the 7-year follow-up in the DNBC was available for 12964 (58%) of the 22439 children invited to participate in the Puberty Cohort (Figure1). Childhood overweight and obesity were associated with earlier pubertal timing even after adjustment for unobserved time-stable confounders shared within families. Feb. 2, 2010— -- Researchers may have found yet another reason not to let boys become obese-- it could delay their puberty. 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 boys (ORs ranged between 1.09 and 1.47; see Table 5). Puberty is the physiological process and crucial developmental stage, typically beginning between 9.5 and 13.5 years of age (average 11.5 years) in boys and lasting normally about 5-6 years, characterized by the gradual transition from childhood to adulthood, with the attainment of appearance of secondary sexual characteristics and mainly of sexual maturity and reproductive capability []. Sandhu J, Ben-Shlomo Y, Cole TJ, Holly J, Davey Smith G.. 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). O'Keeffe LM, Frysz M, Bell JA, Howe LD, Fraser A. Puberty timing and adiposity change across childhood and adolescence: disentangling cause and consequence, Percent body fat at age five predicts earlier pubertal development among girls at age 9. 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). HHS Vulnerability Disclosure, Help The ORs for the association reported by included studies ranged from 1.11 to 9.00. [emailprotected], Jenni Glenn Gingery Growth of pubic hair. Total obesity and central obesity from ages 4 to 7 raised the odds of early puberty compared with having a healthy weight. And puberty may be starting earlier in boys as well. la=en (6 April 2020, date last accessed). Information on current status of the following pubertal milestones was collected: voice break (yes, no), first ejaculation (yes, no; if yes: year and month), menarche (yes, no; if yes: year and month), acne (yes, no), axillary hair (yes, no) and Tanner stages (1 to 5) for pubic hair development and breast development or genital development.40,41 Tanner stages were illustrated with line drawings assisted by a short description of each stage. Adults For adults, WHO defines overweight and obesity as follows: overweight is a BMI greater than or equal to 25; and In the cohort analysis, childhood overweight and obesity were associated with earlier pubertal timing in both boys and girls in a dose-dependent manner. More notably, the children involved in these studies may have already begun puberty, which can also lead to selective bias in the results. Obesity may trigger early puberty or a common genetic or environmental factor may underlie both phenomena (23, 27). The most promising link between obesity and puberty is the adipokine leptin and its interaction with the kisspeptin system, which is an important regulator of puberty. For girls, puberty can begin as early as eight years old, with most instances of early puberty linked to childhood obesity. https://www.dnbc.dk/-/media/arkiv/projekt-sites/dnbc/kodeboeger/pubertetsundersoegelsen/english_pubertyfollowup_codebook_final.pdf? Secondly, case-control studies are prone to recall bias. Obesity is considered a global health problem affecting more than a third of the population. Among these singletons were 888 brothers and 812 sisters (Figure1). Forest plot of childhood overweight/obesity and the risk of early puberty in boys. Puberty, the transformational period where a child reaches physical and sexual maturity, is a near universal human experience, yet the fundamental processes behind how and when it starts is still a mystery. A total of 1,104 cases with early puberty in 13,338 girls in childhood were identified. Here is a general timeline for physical changes that occur during puberty for boys: Puberty Event. The process can take up to 4 years. Besides, detailed analyses were conducted for more diverse subgroups. Selected characteristic of 3 case-control studies of childhood overweight/obesity and early puberty. Lundeen EA, Norris SA, Martorell R. The ePub format uses eBook readers, which have several "ease of reading" features Childhood overweight and obesity and timing of puberty in boys and girls: cohort and sibling-matched analyses, GUID:D5741256-F364-46DC-80AE-C2D61A87CB15.

In addition, early voice breaking was defined as age at voice breaking earlier than 13 years. The ePub format is best viewed in the iBooks reader. The good news is that despite girls trending toward an earlier age at puberty (breast development), the average age for starting periods has remained about the same. The Swedish Young Male Twins Study showed that boys who matured early had a higher BMI through childhood (12). Chen C, Zhang Y, Sun W, Chen Y, Jiang Y, Song Y, et al.. 18 as such, alterations in diet and exercise exert a powerful influence on pubertal maturation. Meanwhile, we also analyzed the association between childhood overweight/obese and puberty in boys. Endocrine Society is a global community of physicians and scientists dedicated to accelerating scientific breakthroughs and improving patient health and well being. Obesity, paediatric obesity, adiposity, body mass index, puberty, menarche. 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). The characteristics of the 10 included studies are shown in the (Tables 1, ,2).2). Forest plot of childhood overweight/obesity and the risk of early puberty in girls. 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 following search terms were applied in combination: (1) weight, height, body mass index, and BMI; (2) infant, infancy, early, postnatal, childhood, preschool, pre-school, and school; (3) overweight, obesity, adiposity, body composition, and waist circumference; and (4) puberty, adrenarche, pubescence, menarcheal, adolescence, and youth. Subgroup analyses for the association between childhood overweight/obesity and early puberty in girls are shown in Table 4. Li WY, Liu Q, Deng X, Chen YW, Liu SD, Story M.. Association between obesity and puberty timing: a systematic review and meta-analysis. already built in. Is obesity associated with early sexual maturation? Studies were excluded if they: (1) were reviews, case reports, letter to the editor, or abstracts; (2) provided vague or incomplete data; (3) were redundant publications; or (4) included children with any diseases which would affect pubertal development as participants. Sensitivity analyses were conducted to evaluate the robustness of the meta-analysis results, i.e., repeating meta-analyses were conducted after excluding one included study at a time and comparing the results before and after exclusion. will also be available for a limited time. Objectives Obesity is reported to be closely relevant to early sexual development but the relationship between sexual precocity and obesity or central obesity is still inconsistent, especially in boys. Birthweight and parity were obtained from the Danish Medical Birth Registry.44 Highest educational class of the parents was obtained from Statistics Denmark and classified according to the International Standard Class of Occupation and Education codes (ISCO-88 and ISCED). 1 Some males mature faster than their peers, and some physical changes may be more gradual than others. The impact of childhood body mass index on timing of puberty, adult stature and obesity: a follow-up study based on adolescent anthropometry recorded at Christ's Hospital (1936-1964, BMI in childhood and its association with height gain, timing of puberty, and final height. Corresponding author. Subgroup and sensitivity analyses were performed to explore possible sources of heterogeneity and to assess the robustness of the results. You may switch to Article in classic view. By giving leptin to mice lacking it, the researchers were able to control when puberty starts.

But it's different for everyone, so don't worry if your child reaches puberty before or after their friends. On the basis of a large sample size, we received a more convincing result. Heterogeneity was assessed by the Chi-square test (p < 0.05 represented statistically significant heterogeneity) and I2 statistic (I2 > 75% indicated an extremely high level of heterogeneity, 5175% showed a high level of heterogeneity, 2650% demonstrated a moderate-level of heterogeneity, and 25% signified a low level of heterogeneity) (23, 24). Earlier menarche in girls is associated with increased risk of adult obesity, type 2 diabetes and breast cancer. For instance, among boys age 5 or 6, those with obesity had. In addition, obese girls are also at increased risk of hyperandrogenism. Senior Communications Manager, Public Relations NCI CPTC Antibody Characterization Program.

An official website of the United States government. Obesity increases the odds that prostate cancer will spread beyond the gland, and it also makes relapse after treatment more likely. For girls, puberty can begin as early as eight years old, with most instances of early puberty linked to childhood obesity. The inclusion of titles and abstracts was intentionally expanded with a view to obtaining more relevant studies. 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. Girls grow 2-8 inches taller, while boys grow 4-12 inches taller. Reference lists of all reviews related to the topic and other included studies were manually searched for additional probably eligible studies. Obese boys constitute a distinct category of boys with pubertal delay in terms of their growth, but their response to testosterone is similar to that observed in boys with classic CDP. Data was analyzed and compared using three independent RNA sequencing methods. See Int J Epidemiol. Design A large population-based cross-sectional study using multistage, stratified . Sensitivity analyses validated the robustness of the findings. Investigating the relationship between precocious puberty and obesity: a cross-sectional study in Shanghai, China. 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. In boys, overweight and obesity have been reported to have higher,2224 lower24,25 or comparable29 Tanner stages in cross-sectional studies. 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). Although without statistical significance, a higher risk of early puberty was also found in boys who were overweight/obese in childhood (OR: 1.29, 95% CI: 0.981.70). 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. Previous studies found that girls with obesity start puberty and experience their first menstrual period earlier than girls with normal weight. Childhood BMI was derived from height (cm) and weight (kg) reported by the mothers at a median age of 7.1 (25th75th percentile: 7.07.2) years. During the same time, the prevalence of severe obesity increased from 4.7% to 9.2%. Meanwhile, obese children's tissues were exposed to high levels of estrogen, which ultimately leads to early puberty. We thank all our colleagues working in Department of Epidemiology and Health Statistics, Xiangya School of Public Health, Central South University, and Department of Plastic Surgery of Third Xiangya Hospital, Central South University. Huber PJ. Case-control studies are widely considered to be prone to recall and selection biases, which restrict the strength and quality of evidence. A larger number of studies have examined the relationship between adiposity and puberty in girls than in boys and the evidence that obesity leads to an earlier timing of puberty is more . Phone: (202)-971-3611 Influence of obesity on timing of puberty, Childhood obesity and the timing of puberty. Begg's test did not show a potential publication bias (z = 0.42, p = 0.677). These sources of measurement error are most likely non-differential with regard to the childrens pubertal timing that usually occurs a few years later. For boys, the link between adiposity . E-mail: Received 2020 Mar 3; Accepted 2020 Mar 24. Total obesity and central obesity from ages 4 to 7 raised the odds of early puberty compared with having a healthy weight. Maternal smoking in first trimester, maternal pre-pregnancy BMI, and maternal age at menarche were obtained from the first interview in pregnancy scheduled around week 12. Flehmig G, Scholz M, Klting N, Fasshauer M, Tnjes A, Stumvoll M, et al.. The genes that were expressed during pubertal transition were, in part, related to growing axons and dendrites, i.e. Systematic Review Registration Growth during childhood and adolescence occurs at different rates and is influenced by the interaction between genetic and environmental factors. Federal government websites often end in .gov or .mil. 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). We found that higher childhood BMI was associated with earlier pubertal timing in boys and girls in both a cohort analysis and a sibling-matched analysis. We will refer to the analysis of these children as the cohort analysis. 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.. before puberty can occur, a critical body weight or fat mass must be achieved. [emailprotected]. The US obesity prevalence was 41.9% in 2017 - March 2020. An increased risk of early puberty related to childhood overweight/obesity was also found in boys, although the estimate was not statistically significant. Subgroup analyses for the association between childhood overweight/obesity and early puberty in boys. Childhood obesity can be addressed with exercise and nutrition. To determine central obesity, study personnel measured each boys waistline. For instance, among boys age 5 or 6, those with obesity had nearly 2.7 times the odds of starting puberty early, and those with central obesity had almost 6.4 higher odds of puberty before age 9 . Additionally, several studies did not find a significant association between childhood obesity and early puberty (1517). In the United States, the prevalence of obesity in 6 to 11-year-old children rose from 7% in 1980 to nearly 18% in 2012. An American Cancer Society study of 404,576 men demonstrated the link: being overweight increases a man's risk by 8%, being obese boosts risk by 20%, and being severely obese increases risk by 34%. Puberty is second to the prenatal period in rapid growth as the long bones stretch to their final adult size. The team found a positive and statistically significant association between total body obesity and precocious puberty from four to seven years of age, with 45 boys (9.1%) starting puberty early. In girls, it can. 10 1/2 to 16 1/2. McCartney CR, Blank SK, Prendergast KA. Of the observational studies included here, seven were cohort in design and three were case-control. precocious puberty and childhood overweight and obesity are important public health problems that both had adverse effects, which including psychological symptom in childhood, short final height or reproductive dysfunction in adulthood, on children's physical and psychological development.the prevalence of precocious puberty and childhood The half-yearly questions on puberty in the Puberty Cohort were identical to the questions on puberty in the 11-year follow-up. For boys, pubertal trends are less clear, but recent data shows similar early onset. Finally, 10 articles were included in meta-analysis (see Figure 1) (13, 19, 20, 2531). et al.

The Society has more than 18,000 members, including scientists, physicians, educators, nurses, and students in 122 countries. Development of adiposity, obesity and age at menarche: an 8-year follow-up study in Portuguese schoolgirls. Silventoinen K, Haukka J, Dunkel L, Tynelius P, Rasmussen F. Genetics of pubertal timing and its associations with relative weight in childhood and adult height: the swedish young male twins study. Bookshelf For example, when case-control studies are used to explore the relationship between smoking and lung cancer, lung cancer patients are likely to have recall bias on their past smoking dose and frequency due to the long incubation period of lung cancer. Qualitative analysis identified that boys with high BMI trajectories had a greater risk of early puberty than boys with low BMI trajectories (13). Unable to load your collection due to an error, Unable to load your delegates due to an error. 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. Only a tendency toward earlier pubertal timing for higher childhood body mass index was observed for brothers in the sibling-matched analysis. Phone: (202)-971-3655 Chen YC, Fan HY, Yang C, Hsieh RH, Pan WH, Lee YL. 81973137 and 82173608). Subgroup analyses for the association between childhood overweight/obesity and early puberty in girls. When stratified by confounders controlled, positive associations between childhood overweight/obesity and early puberty were still found in studies that have none of the confounders controlled (OR: 2.12, 95% CI: 1.433.14), and studies that had one or more confounders controlled (OR: 1.04, 95% CI: 1.001.08). Whereas those with excess belly fat had almost 6.4 higher odds of puberty before age. The second phase involves weight gain related to bone, muscle, and fat tissue development. Bone mineral density and body composition in normal weight, overweight and obese children. The .gov means its official. Early growth predicts timing of puberty in boys: results of a 14-year nutrition and growth study. sharing sensitive information, make sure youre on a federal the display of certain parts of an article in other eReaders. 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. However, in boys the evidence has been controversial.. In the hypothalamus, leptin can stimulate the secretion of kisspeptin, which in turn activates the hypothalamic-pituitary-gonadal (HPG) axis and promotes the secretion of GnRH from hypothalamic arcuate neurons in a dose-dependent manner, thereby accelerating puberty (36). Kelly Y, Zilanawala A, Sacker A, Hiatt R, Viner R.. Nutritional status plays an important role in regulating growth, and excess body weight early in life can influence growth patterns. The questionnaire is available online.42. Zhai L, Liu J, Zhao J, Liu J, Bai Y, Jia L, et al.. Association of obesity with onset of puberty and sex hormones in chinese girls: a 4year longitudinal study, Percent body fat and waist circumference from ages 5 to 9 predict early puberty in girls. Puberty is second to the prenatal period in terms of rapid growth as the long bones stretch to their final, adult size. To look for dose-dependent patterns, we also included childhood BMI as restricted cubic splines with three knots at 14, 16 and 18kg/m2. 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. //Www.Feedfuturehealth.Com/Post/Obesity-And-Puberty-What-S-The-Link '' > < /a > compared to lean subjects were recruited by their general practitioners during gestation.
