The relationships between the timing of solid food introduction and the risk of childhood obesity have been examined previously; however, evidence for the association of timing of infant formula introduction remains scarce. This study aimed to examine whether the timing of infant formula introduction is associated with growth <jats:italic>z<\/jats:italic>-scores and overweight at ages 1 and 3 years. This study included 5733 full-term (\u2265 37 gestational weeks) and normal birth weight (\u2265 2500 and &lt; 4000 g) children in the Born in Guangzhou Cohort Study, a prospective cohort study with data collected at 6 weeks, 6, 12 and 36 months. Compared with infant formula introduction at 0\u20133 months, introduction at 4\u20136 months was associated with the lower BMI, weight-for-age and weight-for-length <jats:italic>z<\/jats:italic>-scores at 1 and 3 years old. Also, introduction at 4\u20136 months was associated with the lower odds of at-risk of overweight at age 1 (adjusted OR 0\u00b772, 95 % CI 0\u00b755, 0\u00b794) and 3 years (adjusted OR 0\u00b750, 95 % CI 0\u00b730, 0\u00b785). Introduction at 4\u20136 months also decreased the odds of overweight at age 1 year (adjusted OR 0\u00b742, 95 % CI 0\u00b721, 0\u00b784) but not at age 3 years. Based on our findings, compared with introduction within the first 3 months, introduction at 4\u20136 months has a reduction on later high BMI risk and at-risk of overweight. However, these results need to be replicated in other well-designed studies before more firm recommendations can be made.<\/jats:p>","DOI":"10.1017\/s000711452200071x","type":"journal-article","created":{"date-parts":[[2022,3,10]],"date-time":"2022-03-10T07:42:05Z","timestamp":1646898125000},"page":"166-174","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":3,"title":["Timing of infant formula introduction in relation to BMI and overweight at ages 1 and 3 years: the Born in Guangzhou Cohort Study (BIGCS)"],"prefix":"10.1017","volume":"129","author":[{"given":"Mingyang","family":"Yuan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minshan","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yixin","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kin Bong Hubert","family":"Lam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinhua","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianrong","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Songying","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongmei","family":"Wei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.
