Abstract:
Objective: To investigate the relationship between serum leptin concentration and diet nutrition, age and gender. Method: One hundred fifty-eight men and women aged 18-72 y were initially drawn from a community in Jinan City. The parameters measured included height, weight and serum leptin concentrations. In addition, a 3-d food record was used to represent usual food intake by the participants. Results: The mean serum leptin concentration in males was 8.38?6.31ng/ml, while in females 24.98?13.29 ng/ml. Serum leptin level in males was significantly correlated with age, but not in females. Respectively, serum leptin level in males and females were not correlated to dietary factors. After adjusted for BMI, serun leptin level in females was positively correlated with dietary intake of fat, MUFA and PUFA. Conclusion: Serum leptin level in female is higher than that in male. Age is correlated to serum leptin level in males. The relation of dietary intake of fat, MUFA and PUFA to serum leptin concentration only existed in women.
