The cross-sectional and longitudinal association of the BODE index with quality of life in patients with chronic obstructive pulmonary disease.

Background: The body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index was shown at predicting the risk of death, exacerbation and disease severity among patients with COPD, but few studies verified relationship between BODE index and health related quality of life (HRQoL) among Chinese COPD patients. The objective of this study was to evaluate the relationship between BODE index and HRQoL in cross-sectional and longitudinal association analyses.

Methods: A multi-center prospective cohort study was initially conducted in 491 stable COPD patients in Beijing, China.

[Blood leptin level of 154 Chinese children 0 - 14 years of age].

Objective: To study blood Leptin level of 154 (78 male, 76 female) Chinese obese/non-obese children aged 0 - 14 years during 1999 - 2001.

Methods: The gender- and age-specific distribution pattern of Leptin and its relationship with anthropometric parameters (waist circumference, waist/hip ratio, lean body mass, fat mass, body fat percentage, BMI/Kaup index etc.) and blood insulin level were recorded.
