Factors associated with obesity in Chinese-American children

Chen JL, Kennedy C

Pediatr Nurs, 2005 Mar-Jun;31(2):110-5.
PMID: 15934563

OBJECTIVE:A cross-sectional study design was utilized to examine factors associated with obesity in Chinese-American children.
SUBJECTS:Chinese-American children (8 to 10 years old) and their mothers (N = 68) in California participated in the study.
MEASUREMENTS:Mothers completed demographic information, the Family Assessment Device, Attitudes Toward Child Rearing Scale, and Suinn-Lew Asian Self-identity Acculturation Scale. Children's body mass index was measured, and children completed a self-administered physical activity checklist, Food Frequency Questionnaire, and the Schoolagers' Coping Strategies Inventory.
RESULTS:Results indicated three variables that predicted children's body mass index: older age, a more democratic parenting style, and poor communication (R2=.263, F=8.727, p = .0001). Children whose mothers had a low level of acculturation were also more likely to be overweight than were children whose mothers were highly acculturated.
CONCLUSION:This study revealed that children's ages, a democratic parenting style, and poor family communication contribute to increased body mass index in Chinese-American children. Other factors related to children's BMI and dietary intake include acculturation level of the mother and family affective responses. Future studies should examine the change in BMI over time and in different age groups and why parenting and family communication impact children's body weight.
Comparative Demographics and Outcomes of Minimally Invasive Transforaminal Lumbar Interbody Fusion in Chinese, Malays, and Indians

STUDY DESIGN: This study carried out a retrospective review of prospectively collected registry data.
OBJECTIVE: This study aimed to determine whether (1) utilization rates; (2) demographics and preoperative statuses; and (3) clinical outcomes differ among Chinese, Malays, and Indians undergoing minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
SUMMARY OF BACKGROUND DATA: There is a marked racial disparity in spine surgery outcomes between white and African American patients. Comparative studies of ethnicity have mostly been carried out in American populations, with an underrepresentation of Asian ethnic groups. It is unclear whether these disparities exist among Chinese, Malays, and Indians.
METHODS: A prospectively maintained registry was reviewed for 753 patients who underwent primary MIS-TLIF for degenerative spondylolisthesis between 2006 and 2013. The cohort was stratified by race. Comparisons of demographics, functional outcomes, and patient satisfaction were performed preoperatively and 1 month, 3 months, 6 months, and 2 years postoperatively.
RESULTS: Compared with population statistics, there was an overrepresentation of Chinese (6.6%) and an underrepresentation of Malays (5.0%) and Indians (3.5%) who underwent MIS-TLIF. Malays and Indians were younger and had higher body mass index at the time of surgery compared with Chinese. After adjusting for age, sex, and body mass index, Malays had significantly worse back pain and Indians had poorer Short-Form 36 Physical Component Summary compared with Chinese preoperatively. Chinese also had a better preoperative Oswestry Disability Index compared with the other races. Although significant differences remained at 1 month, there was no difference in outcomes up to 2 years postoperatively, except for a lower Physical Component Summary in Indians compared with Chinese at 2 years. The rate of minimal clinically important difference attainment, satisfaction, and expectation fulfillment was also comparable. At 2 years, 87.0% of Chinese, 76.9% of Malays, and 91.7% of Indians were satisfied.
CONCLUSION: The variations in demographics, preoperative statuses, and postoperative outcomes between races should be considered when interpreting outcome studies of lumbar spine surgery in Asian populations.
LEVEL OF EVIDENCE: Level III-nonrandomized cohort study.
Efficacy and safety of 2 g/day of strontium ranelate in Asian women with postmenopausal osteoporosis

Strontium ranelate is a new effective anti-osteoporotic treatment having a unique mode of action, reducing bone resorption while promoting continued bone formation, with a broad range of anti-fracture efficacy at vertebral as well as peripheral sites. In Phase III studies, it has proven its early and sustained efficacy against vertebral fractures in Caucasians along with a significant increase in lumbar bone mineral density (BMD). The aim of this randomized double-blind study was to demonstrate the efficacy of strontium ranelate (2 g/day) on lumbar spine bone mineral density and the clinical and biological safety in Asian postmenopausal osteoporotic patients compared to placebo over 1 year. Three hundred and twenty-nine eligible women from mainland China, Hong Kong and Malaysia were randomized into the study. The baseline characteristics were similar in the treatment and placebo groups: mean age of 66.2+/-6.5 years, time since menopause 17.6+/-7.2 years. In the Full Analysis Set (FAS, N=302), the mean baseline lumbar L2-L4 BMD was 0.715+/-0.106 g/cm(2) in the strontium ranelate group and 0.708 +/- 0.109 g/cm2 in the placebo group. The mean baseline femoral neck BMD was 0.575+/-0.074 g/cm2 and 0.566+/-0.069 g/cm2 respectively and mean total hip BMD was 0.642+/-0.080 g/cm2 and 0.631 +/-0.088 g/cm2 respectively. The overall compliance was 91.4% in the study drug group, and 97.4% in the placebo group. After 1 year of treatment, the lumbar spine, femoral neck and total hip BMD in the treated group was significantly increased by 3-5% as compared to placebo. Strontium ranelate was well tolerated. The most frequently reported emergent adverse events were comparable in both groups (60.4% versus 60.0%), with majority of them being mild gastrointestinal disorders. There were no clinically relevant changes in laboratory tests, such as blood routine, hepatic and renal function. It is thus concluded that the effects of 2 g/day strontium ranelate on BMD and its safety profile in this cohort of postmenopausal osteoporotic Asian women were consistent with results obtained from Caucasian women in which the efficacy on the reduction in risk of fracture has been proven.
