Relation between self-recalled childhood physical activity and adult physical activity: The women’s health initiative

Open Journal of Epidemiology 2013年第4期3卷 224-231页

作者： Deborah Goodman Hannah L. Park Marcia Stefanick Erin LeBlanc Jennifer Bea Lihong Qi Kristopher Kapphahn Michael Lamonte Tood Manini manisha desai Hoda Anton-Culver Cancer Center University of Arizona Tuscon Arizona USA Center for Health Research Kaiser Permanente Portland USA Department of Epidemiology University of California Irvine USA Department of Public Health University of California Davis Sacramento USA Department of Social and Preventive Medicine University at Buffalo Buffalo USA Institute on Aging University of Florida Gainesville USA S Stanford Prevention Research Center Stanford University Palo Alto USA

Background: Evidence suggests that childhood physical activity may play a role in the etiology and prevention of adult chronic diseases. Because researchers must often depend on self-recalled physical activity data many years after the exposure, it is important to understand factors which may influence adult recall of childhood physical activity. This study evaluated the influence of adult characteristics on reported childhood physical activity and the association between adult physical activity and self-recalled childhood physical activity. Methods: 48,066 post-menopausal women from the Women’s Health Initiative Observational Study reported their physical activity level during ages 5-9, 10-14, and 15-19. Results: In this cohort, over 65% of the population reported the same category of physical activity over the three childhood age groups. While higher levels of childhood physical activity were significantly associated with higher adult physical activity, this association varied by race/ethnicity, education, smoking, body mass index, history of diabetes or cardiovascular disease, social support and physical functional status. Women who were consistently highly active reported adult physical activity levels that were 2.82 MET-hr/week (95% C.I. = 2.43, 3.20) higher compared to women who were always physically inactive during childhood. Conclusions: It is important for researchers to understand the influence of adult characteristics on reported childhood physical activity.

Transformation of Sucrose to Starch and Protein in Rice Leaves and Grains under Two Establishment Methods

引用

Rice science 2016年第5期23卷 255-265页

作者： manisha KUMARI Bavita ASTHIR Department of Biochemistry Punjab Agricultural University

Six rice varieties, PR120, PR116, Feng Ai Zan, PR115, PAU201 and Punjab Mehak 1 were raised under aerobic and transplanting conditions to assess the effects of planting conditions on sucrose metabolising enzymes in relation to the transformation of free sugars to starch and protein in flag leaves and grains. Activities of sucrose synthase, sucrose phosphate synthase and acid invertase increased till flowering stage in leaves and mid-milky stage（14 d after flowering） in grains and thereafter declined in concomitant with the contents of reducing sugar. Under aerobic conditions, the activities of acid invertase and sucrose synthase（cleavage） significantly decreased in conjunction with the decrease in non-reducing sugars and starch content in all the varieties. Disruption of starch biosynthesis under the influence of aerobic conditions in both leaves and grains and the higher build up of sugars possibly resulted in their favoured utilization in nitrogen metabolism. Feng Ai Zan, PR115 and PR120 maintained higher levels of sucrose synthase enzymes in grains and leaves and contents of metabolites（amino acid, protein and non-reducing sugar） under aerobic conditions, while PR116, Punjab Mehak 1 and PAU201 performed better under transplanting conditions, thus showing their adaptation to environmental stress. Yield gap between aerobic and transplanting rice is attributed primarily to the difference in sink activity and strength. Overall, it appear that up-regulation of sucrose synthase（synthesis） and sucrose phosphate synthase under aerobic conditions might be responsible in enhancing growth and productivity of rice varieties.
