ABSTRACT

We consider the relationship between time in bed (TIB) and sleeping difficulties with demographic variables and nutrient intakes in the second (T2) and third (T3) trimester of pregnancy. Data were acquired from a volunteer sample of New Zealand pregnant women. In T2 and T3, questionnaires were administered, diets were obtained from one 24 h recall and three weighed food records, and physical activity was measured with the use of three 24 h diaries. In total, 370 women had complete information in T2 and 310 in T3. In both trimesters, TIB was associated with welfare or disability status, marital status and age. In T2, TIB was associated with work, childcare, education and pre-pregnancy alcohol consumption. There were fewer significant lifestyle covariates in T3. In both trimesters, TIB declined with increasing dietary intake, especially water, protein, biotin, potassium, magnesium, calcium, phosphorus and manganese. Adjusted for weight of dietary intake and welfare/disability, TIB declined with increasing nutrient density of B vitamins, saturated fats, potassium, fructose and lactose; and TIB increased with carbohydrate, sucrose and vitamin E. Subjective sleeping difficulties increased with the week of gestation, morning sickness severity, anxiety, dairy and saturated fat intake, and they decreased with fruit, vegetable and monounsaturated fat intake. The study highlights the changing influence of covariates throughout the pregnancy and corroborates several published findings on the relationship of diet and sleep.

ABSTRACT

AIM: To investigate maternal alcohol intakes before and during pregnancy, their impact on mothers and infants to 18 months. METHOD: Prospective study of 504 New Zealand volunteers visited in months 4 and 7 of pregnancy, measurements taken, lifestyle details recorded including alcohol intake before and during pregnancy. Eighteen months after birth, 370 infants were measured, and infant development recorded. RESULTS: Nineteen per cent of mothers never drank, 53% stopped when they knew they were pregnant, 29% continued to drink. Twenty-two per cent of drinkers binge drank (over 50 g alcohol per session) before pregnancy and 10% during pregnancy. Daily drinking was associated with increased obesity in mothers. Alcohol consumption before or during pregnancy was not associated with infant motor development, had a slight negative effect on growth, and a significant association with vocal ability to 18 months. Energy intake appeared to partially moderate this effect. CONCLUSION: Maternal alcohol consumption exceeding 50 g per session both before and during pregnancy was associated with decreasing vocal ability in the 18-month old infant.

ABSTRACT

The association between water and nutrient intake in pregnant women, and wheeze in their 18 month old infants, was investigated in a prospective study. Volunteers (n=369) recruited from northern New Zealand were visited in months 4 and 7 of pregnancy. At each visit anthropometric measurements were taken, diet assessed by 24-hour recall and 3-day food records and questionnaires determining personal details administered. Eighteen months after birth, infants were measured, and questions on infant feeding and wheeze asked. Overall, mothers reported 32% of their infants had wheezed in the last 12 months. After adjusting for significant covariates and energy intake, higher maternal intakes of dietary water (p=0.009) and manganese (p=0.024) were associated with decreased wheeze, and glucose (p=0.003) with increased wheeze. Prevalence of infant wheeze decreased 18.5% from the lower to the upper quartile of water intake, and 17.4% from the lower to the upper quartile of manganese intake. Wheeze was more common in Polynesian than European infants (41.8% vs 28.9%). Polynesian mothers consumed significantly less dietary water (median 451 g less) and manganese (median 1374 µg less) than European mothers per day. Glucose was only significant because of strong association with infant wheeze at extremely high maternal intakes of >40 g/day in ~10% of the subjects. There was no association between maternal dietary supplement intake and wheeze. Mothers estimated at high risk of infant wheeze consumed less tap water, whole grains, tea, fruit; and more fruit juice, soft drink, processed meat and fish products, and refined grain products. This is the first study to report an intergenerational association between maternal water, and glucose intake with infant wheeze.

ABSTRACT

To investigate the association of subcutaneous body fat levels in pregnant women with wheezing in their 18 month old infants. A prospective study of European and Polynesian volunteers (n = 369) recruited from northern New Zealand were visited in months 4 and 7 of pregnancy when height, weight, and triceps, biceps and costal skinfolds were measured, and questionnaires determining personal details administered; and again visited 18 months after birth when infants were measured and questions on infant feeding and wheeze administered. At 18 months 32 % of infants had wheezed in the past 12 months. Increased wheeze was associated with maternal asthma, eczema or allergy (p = 0.001); receiving family welfare payments (p = 0.010); and being Polynesian (p = 0.021); while exclusive breastfeeding to 2 months (p = 0.045) was associated with decreased wheeze. Individual month 4 and month 7 mean triceps, biceps and costal skinfolds were all greater in mothers of wheezers compared to nonwheezers, biceps and costal skinfolds significantly so (p = 0.002, p = 0.005 at month 7). The sum of these skinfolds at month 4, at month 7, and the difference between these sums, were all significantly associated with increased risk of infant wheeze at 18 months when considered alone (p = 0.037, p = 0.001 and p = 0.015) or in combination. Prevalence of infant wheeze was 22.7 % for mothers with lower quartile month 7 skinfolds, compared to 45.0 % for mothers with upper quartile. After adjusting for significant covariates the difference in skinfolds had the strongest association (p = 0.003) followed by sum at month 4 (p = 0.074 or 0.003 depending on whether Polynesian ethnicity was included in the model). The sum of skinfolds declined between month 4 and month 7 in 34 % of women. Prevalence of wheeze was 19.2 % where the difference in mothers' skinfolds between month 4 and month 7 decreased by 10 mm or more and 41.7 % where the difference increased by 10 mm or more. Mean month 4 weights, BMI and sum of skinfolds were below average in the latter group. As the sum of month 4 or month 7 maternal skinfolds increased the prevalence of infant wheeze increased. In addition as the change in skinfolds between month 4 and month 7 became more positive the prevalence of infant wheeze increased. This study suggests for the first time that changes in subcutaneous fat during pregnancy are associated with prevalence of infant wheeze.
