Preterm born 9-year-olds have elevated XXXX and low @entity4090 , but levels vary with behavioural and @entity1277 .

AIM: This study examined the relationship between hypothalamic-associated hormones and behavioural and @entity1277 in @entity1 with low birthweight. METHODS: We included 100 @entity1 (mean age 9.7 years): 39 were born preterm at <32 gestational weeks, 28 were full-term, but small for gestational age, and 33 were full-term controls. Behavioural histories were analysed, together with fasting blood samples of leptin, @entity442 ), @entity4090 , glucagon and @entity701 . RESULTS: Preterm @entity1 had lower @entity4090 (p  =  0.01) and higher @entity442 than controls (p  <  0.05, adjusted for confounders), despite being significantly shorter than the predicted target height (p  <  0.001). More preterm @entity1 displayed @entity74 (38% versus 10%, p  <  0.001) and @entity1277 (26% versus 8%, p  <  0.05) than full-term @entity1 . These disorders were associated with lower leptin (p  <  0.01), insulin (p  <  0.05) and @entity442 (p  <  0.05), but correlations between these hormones and leptin were similar among the groups. Combined behavioural and @entity1277 were only observed in preterm @entity1 , who were also the shortest in height. CONCLUSION: Behavioural and @entity1277 among preterm @entity1 were associated with low leptin, insulin and @entity442 . Low @entity4090 in all preterm @entity1 indicated an increased dopaminergic tonus, which might inhibit body weight incrementation. This raises speculation about @entity2856 insensitivity.
