BACKGROUND/OBJECTIVES: Nutritional status and food intake during pregnancy and lactation can affect fetal programming. In the current metabolic syndrome epidemic, high-fructose diets have been strongly implicated. This study investigated the effect of maternal high-fructose intake during pregnancy and lactation on the development of metabolic syndrome in adult offspring. SUBJECTS/METHODS: Drinking water with or without 20% fructose was administered to female C57BL/6J mice over the course of their pregnancy and lactation periods. After weaning, pups ate regular chow. Accu-Chek Performa was used to measure glucose levels, and a tail-cuff method was used to examine systolic blood pressure. Animals were sacrificed at 7 months, their livers were excised, and sections were stained with Oil Red O and hematoxylin and eosin (H&E) staining. Kidneys were collected for gene expression analysis using quantitative real-time Polymerase chain reaction. RESULTS: Adult offspring exposed to maternal high-fructose intake during pregnancy and lactation presented with heavier body weights, fattier livers, and broader areas under the curve in glucose tolerance test values than control offspring. Serum levels of alanine aminotransferase, aspartate aminotransferase, glucose, triglycerides, and total cholesterol and systolic blood pressure in the maternal high-fructose group were higher than that in controls. However, there were no significant differences in mRNA expressions of renin-angiotensin-aldosterone system genes and sodium transporter genes. CONCLUSIONS: These results suggest that maternal high-fructose intake during pregnancy and lactation induces metabolic syndrome with hyperglycemia, hypertension, and dyslipidemia in adult offspring.

Objectives: Pre-pregnancy diet has an important role in preparing for healthy generation. However, evidence on this issue has been scarce. A scoping review synthesising current evidence will support the demand to map 'what has been researched' on pre-pregnancy diet and maternal and child health. Methods: Systematic search was performed using PICOS (Population, Intervention, Comparison, Outcomes, and Study design) framework in electronic databases. Articles were screened for eligibility, summarized, and the quality was assessed using the National Institute of Health assessment tool. The review structure complies with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guide. Results: Forty-two articles were included after full-text screening. Twenty-five studies were in high-income countries (HICs), six in each upper-middle income, five in lower-middle income countries (LMICs), and one in low-income countries (LIC). Based on the regions: North America (n=16), Europe (n=5), South America (n=4), Australia (n=4), Asia (n=5), Middle East (n=2), and sub-Saharan Africa (n=1). The two-most observed diet-related exposures were dietary pattern (n=17) and dietary quality (n=12). The most assessed outcome was gestational diabetes mellitus (n=28) and fetal and newborn anthropometry (n=7). The average quality score±standard deviation was 70±18%. Conclusions: Research related to pre-pregnancy diet is still concentrated in HICs. The context of diet may vary; therefore, future research is encouraged in LMICs and LICs context, and Mediterranean, South-East Asia, Pacific, and African regions. Some maternal and child nutrition-related morbidity, such as anemia and micronutrient deficiencies, have not been discussed. Research on these aspects will benefit to fill in the gaps related to pre-pregnancy diet and maternal and child health.

본 연구는 서울소재의 종합병원 산부인과에 외래로 방문한 임신부 248명을 대상으로 설문조사를 실시하였고, 임신 중 스트레스 정도와 영양섭취상태 및 임신결과와의 관계를 알아보고자 하였다. 조사를 통해 얻어진 결과를 요약하면 다음과 같다. 1) 조사대상자의 나이는 두 군이 비슷하였고, 스트레스 낮은 군이 스트레스 높은 군보다 교육수준, 경제 수준이 약간 높았으나 통계적으로 유의한 차이는 없었다. 스트레스 낮은 군은 스트레스 높은 군에 비해 취업률이 높게 나타났다 (p < 0.05). 가족 수에서는 스트레스 높은 군이 스트레스 낮은 군보다 3인 이상 가족구성의 비율이 높았다 (p < 0.01). 2) 신체 계측치에서 스트레스 높은 군이 키가 작고 임신전 체중이 높았으나 통계적인 유의성은 없었다. 임신 전 BMI는 스트레스 낮은 군보다 스트레스 높은 군에서 과체중 및 비만이 유의적으로 높았다 (p < 0.05). 3) 임신 중 활동은 스트레스 낮은 군이 스트레스 높은 군보다 가벼운 정도의 활동을 하고 있었으며 (p < 0.05), 임신 중 규칙적인 운동은 스트레스 낮은 군이 스트레스 높은 군보다 더 많이 하고 있었다 (p < 0.01). 4) 임신 중 스트레스 요인으로는‘아기에 대한 걱정’ (40.4%),‘건강에 대한 걱정’ (28.8%),‘경제적 어려움’ (13.2%),‘우울감’ (10.1%),‘가족관계’ (2.9%),‘가사 일에 대한 걱정’ (2.5%),‘인간관계’ (2%) 순으로 나타났다. 5) 대부분의 영양소섭취는 스트레스가 낮은 군이 스트레스가 높은 군보다 약간 많았으나 통계적 유의성은 없었다. 엽산, 칼륨, 칼슘, 철의 섭취는 KDRI의 2/3에도 못 미치는 수준이었고 나트륨, 콜레스테롤, 인, 비타민 E는 KDRI의 150% 이상 섭취하고 있었다. 6) 임신 중 스트레스와 섭취한 영양소와의 관계를 보았을 때, 대부분의 영양소와 통계적으로 유의성을 보이지 않았다. 하지만 지방, 콜레스테롤은 섭취량이 많을수록 스트레스 발생 위험도가 높아지는 경향을 보였고, 당질, 식이섬유는 섭취량이 많을수록 스트레스 발생 위험도가 감소하는 경향을 보였다. 7) 스트레스 정도는 두 군에서 임신부의 재태기간, 체중증가량, 신생아 출생 시 체중, 신장 및 Apgar scores와 통계적으로 유의한 차이를 보이지 않았다. 본 연구에서 임신 중 스트레스는 신생아의 건강에 대한 염려, 임신부의 처해있는 경제여건, 사회적 지위나 생활여건, 임신과 관련된 상황, 자신의 성격 및 배우자를 포함한 가족 관계 등 다양한 요인에 의해 나타났다. 본 연구 결과 스트레스 높은 군이 스트레스 낮은 군보다 취업률이 낮았고, 임신전 BMI가 비만 및 과체중군이 많았으며, 임신 중 규칙적인 운동을 하고 있지 않았다. 이런 생활습관들이 임신 중 스트레스에 영향을 미치는 것으로 사료된다. 하지만 임신 중 스트레스는 대부분의 영양섭취상태와 임신결과에 직접적인 영향을 미치지 않았다. 스트레스와 영양소 섭취와의 관련성이 뚜렷하게 나타나지 않은 것은 본 연구에서 임신부의 2일간 식이회상법 자료를 이용해 영양소 섭취실태를 조사하였기에 임신부의 평소식사를 반영하는데 한계가 있었기 때문으로 사료된다. 본 연구에서 임신 중 스트레스를 예방하기 위해서는 적절한 체중관리와 규칙적인 운동이 도움이 될 수 있다는 것을 확인하였다.

It is a common clinical practice to recommend taking iron supplements for pregnant women during gestation. Although it is required to ensure adequate iron stores during pregnancy, there has been some debate over the interference effects of excessive iron load, because it is possible to compete in the transport in the intestine and placenta and in binding to serum proteins of other trace minerals. In this study, maternal and neonatal serum concentrations of Fe, Zn, Cu, Se, Cr, Mn, and Co were assessed along with maternal Fe intakes. A total of 124 pregnant women and their term neonates participated voluntarily in this research. The women were divided into one of the three groups {high Fe intake (HFI), median Fe intake (MFI), and low Fe intake (LFI)} by their total Fe intakes and one of the two groups (Anemic and Normal) by their Fe nutritional status. All the data were compared among the three groups and between the two groups also. Total Fe intakes of HFI, MFI, and LFI groups were 140.8 ${\pm}$ 76.1, 68.0 ${\pm}$ 11.2, and 30.2 ${\pm}$ 8.6 mg/day, respectively. Those of Anemic and Normal groups were 90.1 ${\pm}$ 74.8 and 86.6 ${\pm}$ 46.8 mg/day, respectively. Maternal Hb concentration and Hct were not significantly different among HFI, MFI, and LFI groups but those were significantly different between Anemic and Normal groups. However, neonatal Hb concentration was not significantly different among HFI, MFI, and LFI groups and between Anemic and Normal groups either. Maternal serum Fe concentrations of the three groups, HFI, MFI, and LFI, were similar but that of Anemic group was significantly lower compared to Normal group. However, there was no significant difference in neonatal serum Fe concentrations among the three groups and between the two groups either. Serum concentrations of the other trace minerals in both mothers and neonates were not significantly different among HFI, MFI, and LFI groups and between Anemic and Normal groups. In addition, in the maternal serum, Fe concentration was positively correlated to Zn and Se concentration, respectively. As for the neonatal serum, Fe concentration showed a positive correlation to Zn, Cu, Mn, Se, and Co concentration, respectively. No trace mineral concentration was found to correlate negatively to Fe concentration in both maternal and neonatal serum, The results in this study indicate that Fe intakes of pregnant women, even if it is considerably above the level of estimated average requirement (EAR), may not affect serum Fe concentration in both mothers and neonates. In addition it might not influence adversely on the availability of other trace minerals including Zn and Cu in both mothers and neonates.

임신 전(前) Restricted diet을 먹은 것과 Unrestricted diet을 먹은 group간에 2세의 체중증가에 미치는 영향에는 차이가 없었으며 임신 전(前) 체중변화에 있어서 Restricted diet에 숫컷이 더 예민하였다. 암컷에서는 Recovery diet을 주는 기간에는 Unrestricted group을 거의 쫓아 갔으나 숫컷에서는 그차이가 심하였다. 새끼들의 체중에 있어서 임신동안의 초기와 후기의 식이제한 group은 관계없이 임신전(全)기간 식이제한 group과 Unrestricted group간에 체중의 차이를 나타내었다. 어미의 Nitrogen 배설량에서 보면 섭취량에 대한 배설량의 백분율은 사료섭취량의 증감(增減)에 관계없이 일정하며 배설량은 사료섭취량이 많으면 많이 나가고 적으면 그것에 비례해서 적게 배설되었다. 새끼의 Nitrogen 배설량은 8 group사이에 큰 차이를 보여주지 않고 있다. Birth weight는 임신전(前) Restricted diet이나 Unrestricted diet 영향을 받지 않았으며 임신동안의 Unrestricted group의 새끼가 임신동안 전(全)기간 식이제한을 하였거나 부분적으로 식이제한을 한 group의 새끼보다 Birth weight가 컸다. litter size는 사료섭취량에 영향을 받지 않았다.

This study was aimed to evaluate any influence of environmental factors associated with feeding on infants' growth. One hundred infants(62 males and 38 females) aged 4-9 months were measured for length and were weighed. Their mothers were interviewed using questionnaires including general and environmental characteristics and maternal feeding attitude, ideal body habitus, infant's food behavior, and infant's food behavior, and infant's temperament. A further study was conducted on 29 infants at the time their ages reached 12 months. Their dietary intakes were assessed, and blood hemoglobin and serum ferritin concentrations were measured. Z-scores of weight-for-age(WAZ) and Z-scores of height-for-age(HAZ) of 4-9 month- old infants were not correlated with age, education level, income, weight, and height of their parents. Formula-fed infants had significantly lower WAZ and body mass index (BMI) than those of breast fed infants. WAZ was significantly correlated with maternal feeding attitude, but not with ideal body habitus, infant's food behavior or infant's temperament. WAZ of 12-months after birth because of supplementary foods introduced from 6 months of age. WAZ and BMI were positively correlated with blood hemoglobin concentration. Therefore, to ensure proper growth of infants, efforts should be given to postental factors such as breast-feeding, maternal feeding attitude, adequate iron status as well as prenatal factors.

Maternal body weight, skinfold thickness and circumference measurements were examined in 23 lactating women and 10 nonlactating women longitudinally from 1 week to 12 weeks postpartum. The dietary intakes of Korean lactating and nonlactating women were measured by 24-hour recall method and effects of maternal energy intake on body weight change were analyzed by Pearson correlation. The mean daily energy intake of breast-feeding(BF, n=12), combination of breast and formula-feeding (CF, n=11), and formula-feeding (FF, n=10) mothers were 1941kcal, 187kcal and 1727kcal, respectively. A significant decrease in weight was observed at all group. Weight losses at 12 weeks of postpartum in BF, CF and FF motheres were 3.18kg, 3.91kg and 5.15kg respectively. Weight losses increased as calorie intake decreased (${\gamma}$2=0.3803, p<0.05). The skinfold thickness and circumferences on all regions were decreased significantly except triceps and upper arm circumferences. However, there were no significant differences between lactating and nonlactating women. Anthropometric measurements decreased at the trunk but not at the limbs. Weight change was significantly correlated with changes of the scores for proximal circumference (${\gamma}$2=0.4999, p<0.05). There results suggest that lactation does not promete weight loss in well-nourished women and that the Korean RDA for energy in lactation may be too high.

The concentrations of the immunological substances in breast milk and nutritional status were studied in healthy Korean women of middle socioeconomic class. The subjects were recruited at random from obstetric clinics in Seoul. The nutrients intake, prepregnancy BMI, maternal weight gain during pregnancy were studied. The concentrations of lactoferrin(LF), lysozyme(LZ), sIgA, IgG and C3 in colostrum, in transitional milk, and in mature milk, were measured. To elucidate the effect of nutritional status on immunological substances, each components was compared on the basis of either BMI, weight gain, or protein intake. The highest concentrations of the substances were found in colostrum and decreased as lactation progressed. The decline was more prominent in IgG, C3 and sIgA, and less significant in LZ and LF. The colostrum of standard weight gain group showed higher concentrations compared to lower weight gain group. This difference became smaller as the lactation progresses. BMI and nutrient intake status had less significant effect. Lower sIgA was found in lower BMI, in lower weight gain, and lower protein intake groups compared to standard groups, which indicates sIgA is the most affected substance among the measured by nutritional status.

This study uses the 1999-2009 Korean Time Use Survey to explore how mothers' employment affects parental time spent in activities that may relate to their children's weight. Specifically, it estimates two-part regression models to assess the effects of maternal employment upon the amount of time mothers spend in activities potentially related to their preschool children's eating and physical activity. The findings suggest that working mothers and those mothers who work longer hours allocate significantly less time in food preparation, eating with the child, and supervising the child's physical activity than mothers who are not employed and those who work fewer hours. The paper also finds that spouses of working mothers do not allocate more time to these activities to offset the reduction in mothers' time. Also, using local unemployment rates as instrumental variables, maternal employment is found to allow mothers to spend significantly more time on food preparation and family meals, although its effect on mothers' total childcare time is negative. Several aspects of Korean society may have made the relationship between maternal employment and childhood weight issues different from what was found in other countries.
