Thesis (MNutr (Interdisciplinary Health Sciences. Human Nutrition))--Stellenbosch University, 2008. / INTRODUCTION: Since the start of the Prevention of Mother-to-Child
Transmission (PMTCT) Programme at Dr George Mukhari Hospital in
2001, there has been no evaluation of the effect of formula feeding on the
growth and dietary intakes of enrolled infants.
AIM: The aim of this study was to determine the short-term growth,
anthropometry and dietary intake of infants from two to ten weeks of age
were entered into the PMTCT Programme at the Department of Human
Nutrition at Dr George Mukhari Hospital from two to ten weeks of age.
METHODS: This was a descriptive, longitudinal (eight weeks duration)
study. Anthropometric assessment including length and head
circumference was performed at two weeks of age and thereafter at ten
weeks of age. Weight measurement was performed at age two weeks
(visit 1), six weeks (visit 2) and ten weeks (visit 3). Anthropometric
measurements were compared with CDC 20003 growth charts. Feeding
practices and dietary intake (24 hour diet recall interview) were assessed
at each of the four week interval visits and evaluated according to the
DRIs59. At the third visit, a socio-demographic interview and a usual food
intake interview were performed.
RESULTS: A total of 151 [male (N = 75) and female (N = 76)] infants
completed the study. A total of 110 (72%) mothers resided in the
Soshanguve area and 138 (91%) of the mothers had attended high school.
The majority (75%) of mothers was not generating an income from
employment. Generally, mothers had access to safe drinking water and all
(99%) but two mothers used pre-boiled water before preparing infant
formula. The accuracy and correctness of reconstituting infant formula
decreased with each visit as feeds were increasingly made too dilute. A
total of 124 (82%) infants were exclusively formula fed. The remainder
received water, water with sugar and/or complementary feeds. Mean
energy and macronutrient intakes of both males (N = 65, 87%) and females (N = 61, 80%) were below recommendations at age two weeks.
Of all the macronutrients, fats were consumed the least by both males (N =
67, 89%) and females (N = 66, 87%) at visit 1. Catch up growth was
evident and nutrient intakes improved as the study progressed. The mean
weight gain of all infants from visit 1 to 2 was 1.2 (SD 0.3) kg and 0.9 (SD
0.3) kg from visit 2 to 3 (exceeding the CDC 20003 recommendation for
both male and female infants). The incidence of underweight, wasting and
head circumference-for-age below the third percentile decreased from visit
1 to 3, but the number of stunted infants increased towards visit 3. The
majority of infants in this study grew well in their first ten weeks of life.
Growth accelerated as infants became older and growth faltering improved
by ten weeks of age.
CONCLUSION: Overall, the growth of the infants referred to the PMTCT
Programme at the Department of Human Nutrition at Dr George Mukhari
Hospital would appear to be adequate but mothers’ approach to formula
feeding practices needs to be improved in some aspects of feeding their
infants.
