Association of Nutrient Intake and Pregnancy Outcome with Gestational Weight Gain

Gestational age and infant birth weight are influenced by gestational weight gain. This study was aimed to examine the effects of gestational weight gain on pregnancy outcomes. Pregnant women were recruited at two hospitals in Seoul area. Characteristics and dietary intakes of pregnant women were obtained using 24-hour recall questionnaires. Gestational weight gain was categorized as less (Under-gain) than, within (Recommended gain), or greater (Over-gain) than the Institute of Medicine guidelines. Maternal height and pre-pregnancy weight in the over-gain group significantly higher than under-gain and recommended gain group. Mini dietary assessment score of eating bean has significantly higher in under-gain group than recommended gain group and eating kimchi has significantly higher in under-gain group than over-gain group. Score of eating fruit was significantly higher in over-gain group than other groups. The mean intake of carbohydrate in the recommended gain group were significantly higher than under-gain group, and mean intake of potassium in the over-gain group were significantly higher than under-gain group. Under-gain group showed the high rate of the preterm delivery and low birth weight infant delivery. However recommended gain group showed 46% reduced risk of preterm delivery (OR = 0.54 CI = 0.30-0.98). Risk of macrosomia increased with increasing gestational weight gain (p for trend < 0.05). In conclusion, pregnancy outcomes were influenced by gestational weight gain. Therefore, these finding suggested adequate gestational weight gain according to BMI for reducing the risk of preterm delivery, low birth weight and macrosomia.

Musculoskeletal Symptoms and Related Factors of Golf Caddies / 대한산업의학회지

OBJECTIVE: This study evaluated the complaint rates of musculoskeletal symptoms and investigated the related factors of musculoskeletal symptoms in the caddies. METHODS: For 316 caddies working at 6 regular golf courses, we used the self-recording questionnaires to examine general characteristics, job stress factors, subjective musculoskeletal symptoms designed by NIOSH, working environments, and working contents. RESULTS: The complaint rates of musculoskeletal symptoms according to the musculoskeletal criteria of NIOSH were 41.8% in the leg/knee/ankle/foot, 35.8% in the shoulder, 35.8% in the upper back/lower back, 28.8% in the neck, and 28.5% in the arm/wrist/fingers. Important factors affecting musculoskeletal symptoms were daily working hours during the high-demand season in all anatomical sites except the arm/wrist/fingers. Other related factors were degrees of winding and inclined in the golf courses, violent language and violence of customers, inability to regulate the velocity and work load control, heavy physical burden, instability of employment, and possibility of unemployment according to the specialty of caddies. As a results of multivariate logistic regression analysis, musculoskeletal symptoms of the neck, shoulders, back/lower back and leg/knee/ankle/foot were significantly influenced by working time over 12 hours in the high-demand season, and symptoms of the arm/wrist/fingers by low decision latitude (P<0.05). CONCLUSIONS: The complaint rates of musculoskeletal symptoms in the caddies were affected by working time over 12 hours and low decision latitude against excessively high psychological job demand.
