MyJurnal

Background: Kangaroo mother care (KMC) in low birth weight newborns has been found to be beneficial, but
studies have shown that maternal factors might be of concern in the successful application of KMC.
Aim: To study the influence of maternal factors on growth parameters in low-birth-weight babies with KMC.
Methods: This is a prospective cohort study of 40 low birth weight newborns in our institutions. We randomly
assigned the newborns to the group which received KMC and to the group which received conventional care.
Maternal factors were recorded. We measured weight, length, and head circumferences of newborns daily
for thirty days. Data was processed by SPSS x22.0.
Results: A total of 40 newborns were recruited into the study. Weight parameters were significantly higher
in the KMC group than in the conventional group except for the Z scores. Regarding maternal characteristics,
only gestational age was found to influence the initial and the last head circumference (p=0.035). There were
no differences in maternal age, parity, maternal education, mode of delivery, fetal sex, and initial Apgar score
with any of the growth parameters.
Conclusion: There were no maternal and fetal differences in the growth parameters of the groups, except in
the delayed growth of head circumferences in preterm infants.
Keywords: Growth parameters, KMC method, low birth weight

PMID: 33064935 DOI: 10.1111/jdi.13441

AIMS/INTRODUCTION: The association between gestational diabetes mellitus (GDM) and adverse maternal and perinatal outcomes in twin pregnancies remains unclear. This study was undertaken to highlight risk factors for GDM in women with dichorionic (DC) twins, and to determine the association between GDM DC twins and adverse maternal and perinatal outcomes in a large homogeneous Taiwanese population.

MATERIALS AND METHODS: A retrospective cross-sectional study was carried out on 645 women with DC twins, excluding pregnancies complicated by one or both fetuses with demise (n = 22) or congenital anomalies (n = 9), who gave birth after 28 complete gestational weeks between 1 January 2001 and 31 December 2018. Univariable and multiple logistic regression analyses were carried out.

RESULTS: Maternal age >34 years (adjusted odds ratio 2.52; 95% confidence interval 1.25-5.07) and pre-pregnancy body mass index >24.9 kg/m2 (adjusted odds ratio 2.83, 95% confidence interval 1.47-5.46) were independent risk factors for GDM in women with DC twins. Newborns from women with GDM DC twins were more likely to be admitted to the neonatal intensive care unit (adjusted odds ratio 1.70, 95% confidence interval 1.06-2.72) than newborns from women with non-GDM DC twins. Other pregnancy and neonatal outcomes were similar between the two groups.

CONCLUSIONS: Advanced maternal age and pre-pregnancy overweight or obesity are risk factors for GDM in women with DC twins. Except for a nearly twofold increased risk of neonatal intensive care unit admission of newborns, the pregnancy and neonatal outcomes for women with GDM DC twins are similar to those for women with non-GDM DC twins.

PMID: 28975676 DOI: 10.1111/jhn.12519

BACKGROUND: Although growing evidence suggests that dietary patterns associated with noncommunicable diseases in adulthood may develop early in life, when these are established, as well as their determinants, remains unclear.

METHODS: We examined determinants and tracking of a dietary pattern (DP) associated with metabolic risk and its key food groups among 860 adolescents in the Western Australian Pregnancy (Raine) Cohort study. Food intake was reported using a food frequency questionnaire (FFQ) at 14 and 17 years. Z-scores for an 'energy-dense, high-fat, low-fibre' DP were estimated by applying reduced rank regression at both ages. Tracking was based on the predictive value (PV) of remaining in the DPZ-score or food intake quartile at 14 and 17 years. Early-life exposures included: maternal age; maternal pre-pregnancy body mass index; parent smoking status during pregnancy; and parent socio-economic position (SEP) at 14 and 17 years. Associations between the DPZ-scores, early-life factors and SEP were analysed using regression analysis.

RESULTS: Dietary tracking was strongest among boys with high DPZ-scores, high intakes of processed meat, low-fibre bread, crisps and savoury snacks (PV > 1) and the lowest intakes of vegetables, fruit and legumes. Lower maternal education (β = 0.09, P = 0.002 at 14 years; β = 0.14, P

A macroscopic approach to demography

Smith JD

J Math Biol, 2004 Jan;48(1):105-18.

PMID: 14685774

A canonical/lognormal model for human demography is established, specifying the net maternity function and the age distribution for mothers of new-borns using a single macroscopic parameter vector of dimension five. The age distribution of mothers is canonical, while the net maternity function normalizes to a lognormal density. Comparison of an actual population with the model serves to identify anomalies in the population which may be indicative of phase transitions or influences from levels outside the demographic. Tracking the time development of the parameter vector may be used to predict the future state of a population, or to interpolate for data missing from the record. In accordance with classical theoretical considerations of Backman, Prigogine, et al., it emerges that the logarithm of a mother's age is the most fundamental time variable for demographic purposes.

Fulltext A review of determinant factors of stillbirths in Malaysia

Rosnah Sutan

Malaysian Journal of Community Health, 2008;14(2):68-77.

MyJurnal

Introduction : Stillbirth is one of the important adverse pregnancy outcomes that has been used as a health indicator for the measurement of the health status of a country especially for its obstetric care management. However, the aetiology of the occurrence of the stillbirth was commonly difficult to identify because of limitations in the classification system.
Methods : A review of existing, available information published up to January 2007 on stillbirths in Malaysia was used to obtain the basic background on the determinant factors of stillbirths. Results : Malaysia, which is a fast developing country, reported a stillbirth rate in the range of 4 to 5 per 1000 births. Almost 30- 40% were recorded as normally formed macerated stillbirths. This was based on a rapid reporting system of perinatal deaths using the modified version of the Wigglesworth’s pathophysiology classification. Those of extreme maternal age (less than 19 years and more than 35 years), those reside in rural areas, of the ‘Bumiputera’ and Indian ethnic groups were at higher risk of stillbirth. On detailed analysis it was seen that the risks of having a normally formed macerated stillbirth increased among those who had a preterm delivery and hypertension. Stillbirth rates were also higher in those with shorter gestational age and in those with parity between 2 and 5. No other factors related to stillbirth were found in this review.
Conclusion : This is a review based on existing published data which has a lot of limitation when it comes to analysing other important factors that might be related with the risk of the stillbirth. However, extreme maternal age and mothers from rural areas are the two factors that were persistently found in almost all literature. When these factors are combined with signs of pre term delivery, they indicate that close monitoring needs to be done.

Introduction: Childhood vaccination is proven as the most effective intervention to prevent and reduce children mortality caused by Vaccine Preventable Diseases (VPD). It is a major public health concern globally as there are still existences of vaccine incompletion. Despite good immunization coverage, outbreaks of VPD are still reported from time to time with serious implications. The aim of this study is to assess the association between maternal health literacy with completion of childhood vaccination. Methods: A cross- sectional study design was conducted among mothers with children aged 5 years and below using a face to face interview questionnaire. Data entered and analyzed using SPSS version 22. Chi square was used to look for association between two categorical data. Results:Majority of respondents were mother‘s aged 30’s, Malays (76.1 %), completed secondary education (74.8 %) un-employed (63.8 %).Study showed (98.99%) children completed vaccination however (1.01 %) had incomplete vac-cination. There was significant findings on association between maternal education and partner‘s education, main language, employment status and household income with health literacy. The mean health literacy score among the incomplete vaccination group was slightly lower (36.9) compared to the completed vaccination group (39.4). The problematic health literacy was seen at (17.4 %) and the sufficient health literacy was (82.6%). Conclusion: The finding indicated that there is an association between maternal education, partner‘s level of education with health literacy. The health literacy score among those who completed vaccination was slightly higher. Initiatives focusing on maternal health literacy could further improve vaccination completion among children.

Introduction: Early environmental factors play a major role in shaping the health of an individual. Dietary prefer- ence and habits shaped by parental feeding practice during childhood are likely to persist into adulthood which further determines body weights status. This study aimed to determine the retrospective child feeding practices asso- ciated with obesity risk in young adults. Methods: This was a retrospective cross-sectional study with 176 university students in Kuala Lumpur. Data of maternal age, gestational age and feeding practices were collected retrospectively using Child Feeding Questionnaire (CFQ). Subject’s current socio-demographic data was collected and anthropo- metric measurements were taken using standard protocol. Results: Around 22% of the subjects were overweight/ obese. No significant association was found between child feeding practices with maternal age. A significant asso- ciation (p

Advanced parental age is a risk factor for chromosomal abnormalities in their offspring. Trisomy X or Triple X syn- drome has previously been reported with advanced maternal age. Here we report two (2) cases of Trisomy X with paternal age as risk factor. Generally, Trisomy X individuals show variable physical and psychological manifesta- tions. However, both cases reported here have advanced paternal age as a risk factor; 55 years old (46 years old at conception) for Case 1 with patient having right eye squint, beaked nose, Posterior Misalignment Type Ventricular Septal Defect (PMVSD) and small Patent Ductus Arteriosus (PDA) with failure to thrive and 49 years old (45 years old at conception) for Case 2 with speech delay and protruding tongue. In view of that, advanced paternal age could possibly contribute the accumulation of de novo mutations in germ line mosaicism.

Objectives: Chromosomal abnormalities especially aneuploidies are the most common etiology for pregnancy loss. Trisomy 13, trisomy 18 and trisomy 21 are the most common chromosome autosomal aneuploidies with trisomy 21 (Down syndrome) being the most common chromosomal abnormality among liveborn infants. In previous reports, we noted that the recurrence of these aneuploidies in some families may not occur by chance alone.

Methods: Extraction of relevant data from review of medical case notes of a young couple with two offspring with Down syndrome (DS) and Patau syndrome.

Results: A family history of DS is a predisposing factor for both DS and other types of aneuploidy. Certain instances of non-disjunction error are not random.

Conclusion: As the maternal age was not advanced in both pregnancies, there is a possibility that the recurrent aneuploidy in this family may not be accounted by chance alone. The risk of having subsequent affected pregnancy cannot be ignored in this family and prenatal diagnosis is strongly recommended in the subsequent pregnancy.

The relationship between zinc and infant birth weight is still contradictory and up until today there is still no research on this issue done in Iran. This unmatched case control study to evaluate the association between plasma cord blood zinc and infant birth weight at the time of delivery was carried out in the labor ward, Fatemieh Hospital, Hamadan, Iran from the 6 th December 2009 to 18 October 2010. Plasma venous cord blood zinc was measured by AtomicAbsorption Spectro-photometry (AAS) and the weight of 134 Low Birth Weight (LBW) infants (cases) and 134 normal
weight infants (control) were measured at the time of delivery. All mothers with history of chronic diseases, obstetric complications, anemia, twin pregnancy, smoking, using illicit drugs, and alcohol and infants with any obvious anomalies were excluded from this study. Data were analyzed using SPSS version 16. Logistic regression was used to assess the contribution of other risk factors on infant birth weight. The result showed there was significant relationship between infant birth weight and plasma cord blood zinc. The risk of having LBW infant is more than 12 times in mothers who have severe zinc deficiency (OR=12.234,CI 95% 1.122, 133.392, p-value= 0.040). Also in mothers
who have mild to moderate zinc deficiency the risk of having LBW was more than one (OR=1.148, CI 95% 0.358, 3.900, p-value= 0.797). A significant relationship between maternal pre-pregnancy Body Mass Index (BMI) (p< 0.002), maternal weight gain during pregnancy (p< 0.021), previous LBW (p< 0.016), maternal age (p< 0.034) and parity (p< 0.004) with infant birth weight were also found. Logistic regression showed that zinc deficiency along with maternal pre-pregnancy BMI, maternal weight gain during pregnancy, previous LBW, maternal age and parity were predictors
for infant birth weight.

PMID: 12314888

PIP: In Peninsular Malaysia, while the female population aged 15-19 years registered a growth of some 240,000 persons between 1966-1984, the number of births occurring to teenage mothers has decreased by 15,176 from 33,348 to 18,172 during the same period. In 1966, teenage births constituted some 10.8% of the total births but has declined to 4.7% by 1984. A breakdown of the 1984 data by detailed age groups shows that only 0.9% of the teenage births had actually occurred among those below 15 years of age. The declining trend in teenage births, particularly the higher order births among the very young mothers, augurs well for the improvement in family welfare. However, in order to safeguard the health and welfare of mothers and children, concerted efforts should continue to be undertaken to integrate population, family health and family life education into the school curriculum.
