Problem

Gestational diabetes mellitus, defined as any carbohydrate intolerance first diagnosed during pregnancy, is associated with a variety of adverse outcomes, both for the mother and her child.

Aim

To investigate the impact of a structured exercise programme which consisted of aerobic and resistance exercises on the parameters of glycaemic control and other health-related outcomes in pregnant women diagnosed with gestational diabetes mellitus.

Methods

Thirty-eight pregnant women diagnosed with gestational diabetes mellitus were randomised to two groups. Experimental group was treated with standard antenatal care for gestational diabetes mellitus, and regular supervised exercise programme plus daily brisk walks of at least 30 min. Control group received only standard antenatal care for gestational diabetes mellitus. The exercise programme was started from the time of diagnosis of diabetes until birth. It was performed two times per week and sessions lasted 50–55 min.

Findings

The experimental group had lower postprandial glucose levels at the end of pregnancy (P < 0.001). There was no significant difference between groups in the level of fasting glucose at the end of pregnancy. Also, there were no significant differences in the rate of complications during pregnancy and birth, need for pharmacological therapy, maternal body mass and body fat percentage gains during pregnancy, and neonatal Apgar scores, body mass and ponderal index. Neonatal body mass index was higher in the experimental group (P = 0.035).

Conclusion

The structured exercise programme had a beneficial effect on postprandial glucose levels at the end of pregnancy.  相似文献

The objective of this paper is to determine whether the choice of payment schemes (hourly vs. piece rates) is systematically related to the workers' risk aversion and ability. We derive the equilibrium relationship between agents' risk aversion and ability and the power of incentives (payment scheme) in a market where many heterogeneous principals and agents are endogenously matched. The equilibrium matching between principals and agents depends on the traits and is critical in determining the contract choice. Using confidential data from the National Agricultural Workers Survey (NAWS), we find evidence of matching between agricultural workers and the riskiness of their jobs (crops they harvest) based on workers' risk aversion and no matching based on ability. When controlling for matching, we find strong evidence that high risk‐averse workers choose hourly rates and low risk‐averse workers choose piece rates. We also found that high ability types choose piece rates and low ability types choose hourly rates but the evidence is weaker. (JEL J33, D82, Q12)  相似文献

This study evaluated the cross‐cultural measurement invariance of the Pediatric Quality of Life Inventory version 4.0 (PedsQL?) among adolescents sampled from Bulgaria, Croatia, India, Indonesia, Nigeria, Serbia, and Turkey. The multiple‐indicator multiple‐cause (MIMIC) model was used, which allowed controlling of demographic variables (i.e., age, gender, and socioeconomic status). Significant effects of country on scores within the PedsQL? domains were observed, with up to 17 items showing differential item functioning (DIF) across the countries. We did not find support for cross‐cultural measurement invariance hypotheses for scores on the PedsQL? adolescent self‐report in this study. Researchers should use caution in making cross‐cultural quality of life comparisons while using the PedsQL.  相似文献
