Are non-diabetic women with abnormal glucose screening test at increased risk of pre-eclampsia, macrosomia and caesarian birth?

To determine, in non-diabetic women, the relationship of abnormal glucose screening test, with the incidence of pre-eclampsia, macrosomia and caesarian delivery, from 1988-92, 5646 consecutive women attending antenatal clinic were screened with a glucose challenge test (GCT) on their first visit (usually at 16-20 weeks); those with risk factors i.e., history of unexplained perinatal loss, macrosomia or family member with diabetes and an initial abnormal screening test were rescreened at 28-32 weeks, In 482 cases the GCT was abnormal (plasma glucose value was \u3e140 mg% 2 hours after 75g glucose challenge). Of these, 292 had one or more abnormal critical values at a 75g -3 hour oral glucose tolerance test (GTT) and they were treated to maintain euglycaemia. The rest (n=190) had no evidence of glucose intolerance with no abnormal values at the GTT. The subjects were divided into 3 groups based on GCT values; A, randomly selected subjects with a normal GCT (n=1000); B, those with abnormal GCT but normal GTT (n=190); and C, those with abnormal GTT (n=292). The variables studied were age, gravidity, parity, gestational age at delivery, pre-eclampsia, birth-weight and mode of delivery. The incidence of pre-eclampsia and caesarian birth varied, being the lowest in Group A (3.9% and 11.9% respectively) and then rising through group B (6.3% and 16.3% respectively) to the highest in Group C (12.6% and 26.0% respectively; test of linear trend, p\u3c0.05). For macrosomia, the incidence increased from Group A to B but there was a drop in Group C. The incidence of macrosomia was significantly higher for Group B as compared to A or C (9.5% and 3.3%,

Attitudes, Contraceptive Practice and Children Ever Born Among Currently Married Women Exposed to Different Types of Communication Media, Pakistan

The Pakistan population planning programme, in its effort to recruit family planning adopters in order to lower birth rates, has used a broad range of communication media to convey its messages. Mass media like radio, television and cinema have carried the message and field workers have been hired specially to provide the information and services. Various com¬binations of personnel ranging from the illiterate local midwives to educated male-female teams have been tried. The programme has undergone many changes since it was reformulated in 1965. It is currently imparting its messages both through mass media and interpersonal channels. Both male and female workers are still being used at the grassroots level although the set up is undergoing certain organizational and administrative changes

"Like sugar in milk": Reconstructing the genetic history of the Parsi population

Background: The Parsis are one of the smallest religious communities in the world. To understand the population structure and demographic history of this group in detail, we analyzed Indian and Pakistani Parsi populations using high-resolution genetic variation data on autosomal and uniparental loci (Y-chromosomal and mitochondrial DNA). Additionally, we also assayed mitochondrial DNA polymorphisms among ancient Parsi DNA samples excavated from Sanjan, in present day Gujarat, the place of their original settlement in India. Results: Among present-day populations, the Parsis are genetically closest to Iranian and the Caucasus populations rather than their South Asian neighbors. They also share the highest number of haplotypes with present-day Iranians and we estimate that the admixture of the Parsis with Indian populations occurred ~1,200 years ago. Enriched homozygosity in the Parsi reflects their recent isolation and inbreeding. We also observed 48% South-Asian-specific mitochondrial lineages among the ancient samples, which might have resulted from the assimilation of local females during the initial settlement. Finally, we show that Parsis are genetically closer to Neolithic Iranians than to modern Iranians, who have witnessed a more recent wave of admixture from the Near East. Conclusions: Our results are consistent with the historically-recorded migration of the Parsi populations to South Asia in the 7th century and in agreement with their assimilation into the Indian sub-continent's population and cultural milieu "like sugar in milk". Moreover, in a wider context our results support a major demographic transition in West Asia due to the Islamic conquest
