Poor diet quality in pregnancy could impact gestational weight gain (GWG) and consequently fetal growth and development. But today there is limited data available on gestational diet quality. This study investigated the association between diet quality in each pregnancy trimester and GWG in Malaysian women. Diet quality was assessed using the modified Healthy Eating Index for Malaysians (HEI). Total GWG was defined as the difference between measured weight at last prenatal visit and pre-pregnancy weight. About one-fourth of women (23.3%) had excessive total GWG. There were significant differences in the HEI component score across trimesters, except for fruits. Overall, overweight/obese women had lower total HEI score (51.49-55.40) during pregnancy compared to non-overweight/obese women (53.38-56.50). For non-overweight/obese women, higher total HEI scores in the second and third trimesters were significantly associated with lower risk of inadequate GWG (aOR = 0.97, 95% CI = 0.95-0.99, p = 0.01) and higher risk of excessive GWG (aOR = 1.04, 95% CI = 1.01-1.07, p = 0.03), respectively. Overweight/obese women with higher total HEI scores in the second (aOR = 1.04, 95% CI = 1.01-1.07, p = 0.02) and third trimester (aOR = 1.04, 95% CI = 1.01-1.08, p = 0.02) were significantly at higher risk for excessive GWG. Pregnant women had relatively low diet quality throughout pregnancy. Diet quality and GWG association differed according to pre-pregnancy BMI with excessive GWG more likely to be associated with higher total HEI scores in the third trimester.

Associations between prenatal nicotine exposure, oxidative stress, and postpartum visceral fat

Loy SL, Jan Mohamed HJ

Women Health, 2014;54(2):145-60.
PMID: 24329183 DOI: 10.1080/03630242.2013.870632

This study aimed to examine the associations among prenatal nicotine exposure, oxidative stress, and postpartum visceral fat among women exposed to secondhand smoke (SHS). The study was conducted in Kelantan, Malaysia, from April 2010 to December 2012. Blood samples were collected in the second and third trimesters from 135 healthy pregnant women who were followed-up at delivery, 2 months, 6 months and 12 months postpartum. Maternal hair nicotine and oxidative stress markers during pregnancy were measured. Visceral fat was assessed by bioelectrical impedance. Multiple linear regression analysis revealed that maternal hair nicotine concentration was associated with increased DNA damage (tail moment: β=0.580, p=0.001) and decreased glutathione peroxidase (β=-12.100; p=0.009) in the second trimester of pregnancy. Increased DNA damage, protein oxidation and total antioxidant capacity in the second trimester were associated with 2, 6, and 12 months postpartum visceral fat. No direct association was found between prenatal hair nicotine level and postpartum visceral fat; however, these results suggest that any relation of SHS to visceral adiposity may be indirect, mediated via enhanced oxidative stress.

Factors associated with the timing of antenatal care seeking in Bangladesh

Kamal SM, Hassan CH, Islam MN

Asia Pac J Public Health, 2015 Mar;27(2):NP1467-80.
PMID: 24097925 DOI: 10.1177/1010539513485786

This study investigates the factors affecting the timing of antenatal care (ANC) seeking among Bangladeshi women using the 2007 Bangladesh Demographic and Health Survey data. Overall, 52% of the most recently pregnant women sought skilled ANC. The most pronounced reason for not receiving the services was that it was "not needed." Of the women who sought ANC, 57% entered for ANC at the fourth month or later. The multivariate regression analysis revealed that maternal age, women's education, residence, wealth index, pregnancy intention status, child's birth order, and wanting more children were the important determinants of ANC services utilization. Wanting more children and contraception use were no longer independent contributors to late ANC entry. These barriers should also be addressed as part of health interventions through information education and communication programs to early entry to ANC. The need to reduce financial barriers to care is a major implication of this study.

PMID: 31025632

INTRODUCTION: Plasma D-dimer levels rise progressively during pregnancy, so one cannot apply normal reference ranges, or the usual cut-off value (500ng/mL), for the exclusion of venous thromboembolism (VTE), in pregnant women. This study was carried out in pregnant Malaysian women in order to build applicable reference ranges for D-dimer.
MATERIALS AND METHODS: A cross-sectional study was conducted to measure D-dimer in healthy pregnant women, and a non-pregnant control group, using the quantitative HaemosIL D-dimer HS500 assay. Reference ranges were derived using CLSI 'Robust' methods, and differences between group medians were tested using the Kruskal-Wallis and Mann-Whitney U tests.
RESULTS: Plasma D-dimer levels were measured in 92 pregnant women (distributed across the three trimesters)and 31 control women. The medians (and reference ranges) in ng/mL were: control 265 (<799); first trimester 481 (<1070); second trimester 1073 (357-1748); 3rd trimester 1533 (771-2410). There were significant differences between the D-dimer levels of each group and each of the other groups (P<0.001).
CONCLUSIONS: Reference ranges for D-dimer in pregnant Malaysian women have been establised by this study. Whether these ranges can be used to determine cut-off levels for the exclusion of VTE at different stages of pregnancy is doubtful, as the levels rise continuously through pregnancy, and some very high outlying values occur in apparently normal near-term pregnancy.

Introduction: This study aimed to develop and examine the validity and reproducibility of a semi-quantitative food frequency questionnaire (FFQ) among Malay pregnant women in Kelantan, Malaysia.
Methods: A total of 177 Malay pregnant women participated in the validation study while 85 of them participated in the reproducibility study which was carried out in the antenatal clinic of Universiti Sains Malaysia Hospital. The newly developed FFQ was validated against two 24-hour dietary recalls (DR). The FFQ was repeated 20 to 28 days apart.
Results: Results showed that the FFQ moderately over estimated the nutrient and food intakes compared to the DR. Spearman correlation
coefficients for nutrients ranged from 0.24 (fat) to 0.61 (calcium) and for foods, ranged from 0.13 (organ meats, onion and garlic) to 0.57 (malt drink). For nutrients, 72 to 85% of women were classified into the correct quartiles from the FFQ and the DR while for foods, 67 to 85% of women were classified correctly. Bland-Altman plot showed relatively good agreement between these two dietary methods. The intra-class correlation (ICC) was used to estimate reproducibility. It ranged from 0.75 (vitamin C) to 0.94 (phosphorus) for nutrients while it ranged from 0.73 (confectionary) to 0.96 (coffee) for foods.
Conclusion: On average, at least 90% of pregnant women were correctly classified into the quartiles for nutrients and foods from the two sets of the FFQ. The FFQ presented acceptable reproducibility and appears to be a valid tool for categorising pregnant women according to dietary intake.

Fulltext Risk factors for antenatal hypovitaminosis D in an urban district in Malaysia

Bukhary NBI, Isa ZM, Shamsuddin K, Lin KG, Mahdy ZA, Hassan H, et al.

BMC Pregnancy Childbirth, 2016 07 13;16(1):156.
PMID: 27411716 DOI: 10.1186/s12884-016-0939-3

BACKGROUND: Pregnant women form one of the high risk groups facing hypovitaminosis D. Low level of vitamin D will affect directly or indirectly both mother and fetus. Screening vitamin D in the first trimester of pregnancy is important to determine the necessary preventive action. Therefore, this study was aimed to determine the prevalence of hypovitaminosis D and its risk factors among pregnant women in the first trimester.
METHODS: A cross sectional study was carried out among first trimester pregnant women during their first antenatal visit. Samples were taken from different ethnicities in an urban district in Malaysia. A total of 396 respondents (99 % response rate) aged 18-40 years completed self-administered and guided questionnaire (characteristics and risk factors), validated semi-quantitative food frequency questionnaire for vitamin D in Malaysia (FFQ vitamin D/My), anthropometric measures (weight and height), blood test for serum 25(OH)D, skin measurement using Mexameter (MX 18) and Fitzpatrick Skin Type Chart Measurement (FSTCM). Data were analyzed to determine the association between risk factors and hypovitaminosis D.
RESULTS: The prevalence of hypovitaminosis D (serum 25(OH)D
