Observations on the health of infants at a time of rapid societal change: a longitudinal study from birth to fifteen months in Abu Dhabi

Background

Rapid economic and cultural transition in the United Arab Emirates has been accompanied by a rise in chronic disease. Early childhood is known to affect health outcomes in adulthood. This prospective longitudinal study examined the general health of Emirati infants born in a government maternity hospital in the Emirate of Abu Dhabi in October 2002.

Methods

One hundred twenty-five women, who had recently given birth, were interviewed as part of a larger study encompassing a wide range of cultural, social, and behavioural aspects of health. They were then re-interviewed at three (n = 94), six (n = 59) and 15 months postpartum (n = 52). Data are presented using univariate statistics.

Results

In this study seven infants (6%) were born prematurely and four infants (3%) were classified as small for gestational age, while 11 (9%) of the infants weighed less than 2500 g. Low birth weight infants (LBW) were significantly more likely to require treatment in the neonatal intensive care unit (OR = 30.83, p = 0.00). Iron supplementation during pregnancy was associated with fewer underweight infants (OR = 3.92, p = 0.042). No associations were found between infant birth weight and maternal age, age at marriage, consanguinity, education level, current maternal employment, parity, pre-existing anaemia or anaemia in pregnancy, diabetes, folic acid intake, multivitamin intake or infant gender.

Maternally-reported infant health issues, vaccination, medication, breast-feeding and infant nutrition, and use of secure car seats are also reported.

Conclusions

The health of infants at birth in this UAE sample showed improvements compared to previous studies. The proportion of LBW infants is decreasing and continuing improvements in health care in the UAE are having a positive impact on infant health.

Clinical outcome and cost of treatment and care for neonates less than 1000 grams admitted to Vali-e ASR Hospital

BACKGROUND

The aim of this study is to estimate the cost of care and treatment for extremely low birth weight (ELBW) neonates admitted to a teaching and referral hospital. This cost estimation project can help health policy makers and planners make decisions and develop plans for perinatal service staging programs and better management of NICUs (Neonatal Intensive Care Units).

METHODS

This cohort study performed on 50 extremely low birth weight neonates (w ≤ 1000gr) born in Vali-e Asr Hospital, Tehran-Iran in the period of March 2012 to September 2013. This teaching and referral hospital had 15 NICU beds as well as an active neonatal growth and development follow-up clinic with a pediatric neurodevelopment specialist during the period of the study. Cases would undergo initial developmental visits and preventative measures immediately after being admitted to the ward. Also after discharge, they were followed up monthly for six months and then every two months, during first year of life.

RESULTS

Overalls, 23 newborns -46% of ELBW and 40% of total neonatal mortality rate (that amounted 55) died during hospital stay. Beside hospitalization, the major part of expenses was related to medication and medical supplies. All neonates needing rehabilitation underwent this type of intervention for one year. The mean cost of rehabilitation in neonates with no insurance coverage was 6700 US Dollars per year, which is reduced by half (3350 US Dollars) when covered by insurance.

CONCLUSION

Medication, medical supplies and equipment cost was significantly high. This is especially due to the fact that the present types of insurances do not cover such expenses very well, forcing parents to pay themselves. Insurance systems are expected to take this issue into immediate account.

Identification of important and potentially avoidable risk factors in a prospective audit study of neonatal deaths in a paediatric hospital in Vietnam

AIM

Neonatal deaths (≤28 days) account for more than half of child mortality in Vietnam. Presumably most die in hospital, but data are scarce. This study aimed to identify risk factors of death among hospitalised neonates.

METHODS

We prospectively studied all neonatal deaths and expected deaths (discharged alive after withdrawal of life-sustaining treatment) in a Vietnamese tertiary paediatric hospital during a 12-month period in 2009-2010. The medical files were audited classifying admission prognosis, discharge outcome, cause of death/expected death according to two classifications, and important and potentially avoidable risk factors during the hospital stay.

RESULTS

Among 5763 neonates admitted, 235 deaths and 67 expected deaths were included. According to both classifications, major causes were congenital malformations, prematurity and severe infections. Six risk factors were identified in 85% (60/71) of the neonates with a relatively good prognosis: recognition or response to danger signs, internal transfers, nosocomial infections, sepsis management, access to usual equipment/staff, and family perception.

CONCLUSION

Among 302 neonatal deaths/expected deaths, the major causes were congenital malformations, prematurity and severe infections. Six important and potentially avoidable risk factors could be addressed in the subgroup with relatively good admission prognosis, without implementing new technology or major organisational changes.

Differences in vitamin D status and calcium metabolism in Saudi Arabian boys and girls aged 6 to 18 years: effects of age, gender, extent of veiling and physical activity with concomitant implications for bone health

Objective

Few data exist looking at vitamin D status and bone health in school-aged boys and girls from Saudi Arabia. The present study aimed to determine the extent of poor vitamin D status in school boys and girls aged 6–18 years and to examine if there was any difference in status with age, physical activity and veiling and concomitant effects on bone.

Design

Cross-sectional study.

Setting

Jeddah, Kingdom of Saudi Arabia.

Subjects

A total of 150 boys (7–16 years) and 150 girls (6–18 years) from local schools were divided into age categories: 6–9 years (elementary school); 10–12 years (secondary school); 13–14 years (middle years); 15–18 years (high school).

Results

Vitamin D status was significantly lower in girls than boys in all age groups (P < 0·01), with the 15–18-year-old girls having the lowest level (22·0 (sd 9·4) nmol/l) in comparison to the 15–18-year-old boys (39·3 (sd 14·0) nmol/l) and the 6–9-year-old girls (41·2 (sd 9·3) nmol/l). Parathyroid hormone status was highest in the 15–18-year-old girls in comparison to boys of the same age. A total of 64 % of 15–18-year-old girls had 25-hydroxyvitamin D (25OHD) status <25 nmol/l in comparison to 31 % in the 13–14 years age category, 26 % in the 10–12 years category and 2·5 % in the 6–9 years category. No boys had 25OHD status <25 nmol/l. Fully veiled girls had lower 25OHD status than partly veiled or unveiled girls (P < 0·05). Low 25OHD and high parathyroid hormone was associated with lower bone mass in the 6–9 years and 13–14 years age groups (P < 0·05).

Conclusions

These data suggest significant hypovitaminosis D in older adolescent females, which is a cause for concern given that there is currently no public health policy for vitamin D in the Kingdom of Saudi Arabia.

Mutations of a country: a mutation review of single gene disorders in the United Arab Emirates (UAE)

The United Arab Emirates inhabitants are ethnically diverse, with ancestries from Arabia, Persia, Baluchistan, and Africa. However, the majority of the current five million inhabitants are expatriates from the Asian subcontinent, Middle Eastern, African, and European countries. Consanguineous marriages within most UAE subpopulations are still the norm, leading to the formation of isolates and higher frequencies of recessive conditions. The UAE is ranked sixth in terms of prevalence of birth defects, with more than 270 genetic disorders reported in the national population. The UAE has high frequencies of blood disorders including thalassemias, sickle cell disease, and G6PD. In addition, certain genetic conditions are relatively common including cystic fibrosis, Joubert, and Meckel syndromes. Furthermore, numerous rare congenital malformations and metabolic disorders have been reported. We review the single gene disorders that have been studied at the molecular level in the UAE (which currently stand at 76) and compile the mutations found. Several novel (p.S2439fs) mutations have been reported including c.7317delA in NF1, c.5C>T (p.A2V) in DKC1, c.1766T>A (p.I589N) in TP63, and c.2117G>T (p.R706L) in VLDLR. We hope that this review will form the basis to establish a UAE mutations database and serve as a model for the collection of mutations of a country.

Short-term outcome of very low birth weight infants in a developing country: comparison with the Vermont Oxford Network

OBJECTIVES

To determine the outcome of very low birth weight infants (VLBWI) admitted to a level III NICU in UAE and compare the results to percentiles published by the Vermont Oxford Network (VON).

METHOD

Outcome data were collected retrospectively, using standard definitions, on a cohort of VLBWI 500-1500 g admitted between January 2004 and December 2006.

RESULTS

Of the 173 infants weighing 501-1500 g at birth, 85.6% survived until discharge, which corresponds to the 50th percentile (P50) of VON. Chronic lung disease (CLD) occurred in 12.1% (<P25), death or CLD 26.6%, necrotizing enterocolitis (NEC) 5.8% (<P50), intraventricular hemorrhage (IVH) of any grade 17.5% (P25), grade III or IV IVH in 5% (P25), periventricular leucomalacia (PVL) 2.8% (P50), retinopathy of prematurity stage (ROP) 11.3% (<P10). The mortality and morbidity data for the subgroups of 501-1000 g and 1001-1500 g birth weight are also reported.

CONCLUSION

We report the outcome of VLBWI born in a developing country with high resources. The rates of CLD, IVH and ROP were < or =25th percentile of the VON and mortality, NEC and PVL were in the 50th percentile.
