Optimal gestational weight gain in Chinese pregnant women by Chinese-specific BMI categories: a multicentre prospective cohort study.

Objective: To establish optimal gestational weight gain (GWG) in Chinese pregnant women by Chinese-specific BMI categories and compare the new recommendations with the Institute of Medicine (IOM) 2009 guidelines.

Design: Multicentre, prospective cohort study. Unconditional logistic regression analysis was used to evaluate the OR, 95 % CI and the predicted probabilities of adverse pregnancy outcomes.

Households Hunger: The Key Attribute to Anthropometric Failures of Children in West Oromia (Ethiopia).

Poor nutrition is the underlying cause of child death. However, comprehensive data showing the relationships between dietary-practices, food security, and nutritional status are scant. The present study aimed to examine the association of inappropriate feeding practices and household-hunger with anthropometric measures in children aged 6-23 months.

Effect of ovariectomy on serum adiponectin levels and visceral fat in rats.

This study was aimed to examine the effect of ovariectomy on visceral fat, serum adiponectin levels and lipid profile. Forty-five female Sprague Dawley rats were divided into three groups (n=15 each): ovariectomized group (OVX), ovariectomized plus estrogen-treated group (OVX+E2), and sham-operated group (SHAM). Body weight, abdominal adipose tissues, serum adiponectin and lipid profile were measured and compared among the groups after three-month feeding post-surgery.

[Relation between peptide YY 3-36 and dietary induced obesity resistant rats].

Objective: To study the plasma concentration of peptide YY3 - 36 (PYY3-36) and the expression levels of PYY mRNA of ileum and colon in dietary induced obesity (DIO) and dietary induced obesity resistant (DIO-R) rats and the relation between PYY3-36 and DIO-R rats.

Methods: Thirty-six female SD rats were randomly divided into high-fat diet group (n = 27) and chow fed control group (n = 9), after 13 weeks of either a high-fat diet or chew fed diet, the high-fat diet group was subdivided into DIO and DIO-R group according to the final body weight. Weight gain, caloric intake, the concentration of PYY3-36 and the expression levels of PYY mRNA were measured and compared.

[UCPs and PPARgamma2 mRNA in diet induced obesity resistant rats].

Objective: To explore the expression of uncoupling proteins (UCP) and peroxisome proliferator activated receptorgamma2 (PPARgamma2) mRNA in white adipose of high-fat diet induced obesity resistant rats.

Methods: Thirty-six female SD rats were randomly divided into high-fat diet group (n = 27) and chow fed control group (n = 9), and given either high-fat diet or chow for thirteen weeks. Then the high-fat diet group was subdivided into Dietary Induced Obesity (DIO) and Dietary Induced Obesity Resistant (DIO-R) group according to the final body weight.

[Relationship between serum levels of leptin and glucose, lipids in simple obese children].

Objective: To investigate the relationship between fasting serum levels of leptin, glucose, insulin resistance, lipids in simple obese children.

Methods: Fasting serum levels of leptin and insulin (Fins) were measured by RIA in 42 obese and 42 normally-weighted children matched on age, sex and height, and their total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) were analyzed with enzymatic methods. HOMA-IR and LDL-C were calculated.
