Its association with the Asian-Pacific oscillation （APO） was also investigated.The evaluation results showed that the multi-model ensemble mean （MME） and most of the individual models perform well in reproducing the relatively stronger interannual variability of SST over the North Pacific and tropical eastern Pacific. They can also capture reasonably well the observed in-phase and out-of-phase relationships of the APO with the SST in the above two regions, respectively. Under the RCP4.5 and RCPS.5 scenarios, the interannual variability of the SST over the North Pacific and the tropical eastern Pacific is projected by the MME to be weakened during 2050-99 compared to 1950-99. The majority of the CMIP5 models show the same projection as the MME. Besides, the MME projection indicates that the present relationship between the APO and the SST over those two regions would still be dominant under both RCPs. However, considerable discrepancies exist in the changes of the relationships among the individual models.展开更多

Without intervention, obese children are at risk for negative health consequences and for the increased likelihood of staying obese through adulthood. St. Louis Children＇s Hospital provides HTT （Head to Toe）, an interactive 12-session fimess, nutrition, and social well-being class focuses on adopting healthier lifestyles through daily exercise, and proper nutrition. One program referral method is through a partnership with the hospital＇s HSC （Healthy Start Clinic）, a multi-disciplinary obesity clinic. Pretest and posttest assessments are used to measure changes in body metrics, health behaviors, knowledge, readiness to change, and self-concept. Between August 2011 and May 2016, 485 children and at least one parent or guardian with them were enrolled in the program, and up to 235 children completed at least one pretest- or post-assessment. Analysis determined multiple statistically significant improvements in body metrics, health behaviors, knowledge, including questions related to nutrition and food guidelines, readiness to change assessment, and self-concept. Total knowledge increased by 22%; questions related to nutrition increased by 28.2%, social emotional by 18.9% and physical activity by 17.8%. Findings suggest that the Head to Toe program is effective in improving nutrition, physical activity, social emotional knowledge and behaviors among participants. Childhood obesity is a growing epidemic and creating a relationship with a pediatric obesity clinic can increase the total number of children and teens that are introduced to weight management programs.展开更多
