This study aimed to determine the effect of body mass index (BMI) on bone turnover markers in girls with idiopathic central precocious puberty (ICPP) according to weight status at diagnosis. Methods. Two hundred and eleven girls with ICPP were divided according to their weight status at diagnosis into three groups: normal weight, overweight, and obese. The serum levels of total procollagen type 1 N-terminal propeptide (P1NP), N-terminal midfragment of osteocalcin, \u03b2-C-terminal telopeptide of type 1 collagen, and some biochemical indicators were measured. Associations between variables were evaluated by multiple regression analysis. Results. Serum P1NP concentrations were significantly different among groups (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>p<\/a:mi>\n                        <a:mo>&lt;<\/a:mo>\n                        <a:mn>0.001<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>).

Multiple regression analysis of factors associated with BMI showed that it was correlated with P1NP, follicle-stimulating hormone base, and luteinizing hormone peak in the overweight group and the obese group. Conclusions. Our findings showed that BMI was associated with P1NP, revealing the reduction of bone formation in overweight and obese girls with ICPP. During the diagnosis and treatment of girls with ICPP, attention should be paid to body weight and bone metabolism.<\/jats:p>","DOI":"10.1155\/2023\/6615789","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T17:50:06Z","timestamp":1682704206000},"page":"1-7","source":"Crossref","is-referenced-by-count":3,"title":["Relationship between Body Mass Index and Bone Turnover Markers in Girls with Idiopathic Central Precocious Puberty"],"prefix":"10.1155","volume":"2023","author":[{"given":"Jing","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Laboratory Medicine, West China Second University Hospital, Sichuan University, Chengdu, China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children, Ministry of Education, West China Second University Hospital, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen-jie","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, West China Second University Hospital, Sichuan University, Chengdu, China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children, Ministry of Education, West China Second University Hospital, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-duo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, West China Second University Hospital, Sichuan University, Chengdu, China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children, Ministry of Education, West China Second University Hospital, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuan-jiao","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, Maternal and Child Health Hospital of Qingbaijiang District in Chengdu, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6660-1747","authenticated-orcid":true,"given":"Fan","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, West China Second University Hospital, Sichuan University, Chengdu, China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children, Ministry of Education, West China Second University Hospital, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9813-8812","authenticated-orcid":true,"given":"Yong-mei","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, West China Second University Hospital, Sichuan University, Chengdu, China"},{"name":"Key Laboratory of Birth Defects and Related Diseases of Women and Children, Ministry of Education, West China Second University Hospital, Sichuan University, Chengdu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1111\/1753-0407.12647"},{"key":"2","volume-title":"World Humanitarian Data and Trends","author":"OCHA","year":"2018"},{"key":"3","volume-title":"United Nations Coordinated Support to People Affected by Disaster and Conflict","author":"Global Humanitarian Overview","year":"2019"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1186\/s12887-018-1376-4"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1177\/2042018815611004"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.endoen.2016.08.013"},{"key":"7","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.nutres.2016.12.010","article-title":"Obesity is a concern for bone health and aging","volume":"39","author":"S.
