Spatial and temporal patterns of Ixodes scapularis (Acari: Ixodidae) in southeastern Connecticut.

The spatial distribution and abundance of host-seeking Ixodes scapularis Say (formerly I. dammini) were studied in 10 residential sites in woodlands during 1989-1991. In total, 7,385 larval, 2,202 nymphal, 164 female, and 248 male I. scapularis were collected in Old Lyme, Lyme, East Haddam, and Chester, CT. The majority of host-seeking I. scapularis larvae (84.2%) and nymphs (73.5%) were collected within the woodland plots, whereas a large proportion of the adults were recovered from lawn (36.4%) and transitional areas between lawns and forest (20.9%). The majority (71.1% of 1,244) of all stages of I. scapularis on the lawn were recovered within 1 m of the lawn edge, particularly along woods and stone walls. In contrast, most of the I. scapularis (60.0% of 3,065) collected in the woods were > 3 m from any defined edge and ticks were recovered throughout the forested plots. The abundance of nymphs on the lawns (1.0-29.4 nymphs per ha per sample) and in the woods (17.3-271.5 nymphs per ha per sample) varied significantly among the 10 residences during June and July. The average rate of infection by Borrelia burgdorferi, the causal agent of Lyme disease, in the nymphs was 14.2, 14.1, and 15.5% for 1989, 1990, and 1991, respectively. The abundance of I. scapularis nymphs in the forest was significantly higher in June 1991, than in 1989 or 1990. The risk of exposure to infected nymphs of I. scapularis varied spatially with the landscape and individual residence, and temporally.

Food stamps are associated with food security and dietary intake of inner-city preschoolers from Hartford, Connecticut.

The goal of the present study was to examine the association of the Food Stamp Program with the food security and dietary intake of low-income children from Hartford, CT, who were enrolled in the Supplemental Food Program for Women, Infants, and Children (WIC). We compared the food and nutrition situation of low-income preschoolers who received food stamps (FS, n = 59) with that of those who did not receive food stamps (NFS, n = 40). Children were an average age of 2.7 +/- 0.6 y, and 95% were receiving WIC benefits at the time of the study. Groups were comparable in demographic characteristics, but the socioeconomic status of the FS group was lower than that of the NFS group (P < 0.05). Food security was assessed with the Radimer/Cornell hunger scale, and dietary intake was assessed with a single 24-h recall and a 14-item food frequency questionnaire. Multivariate analyses within the FS group indicated that a monthly duration of food stamps of <4 wk was a predictor of household food security (odds ratio 0.10, 95% confidence interval 0.02-0.56). Food stamp use was associated with above-median energy-adjusted intakes of vitamin B-6 (3.13, 1.16-8.45), folate (2.92, 1.09-7.81) and iron (3.72, 1.31-10.54). The NFS children were more likely to consume <8 mg iron/d (3.73, 1.09-12.80). These results suggest that the Food Stamp Program is associated with food security and preschoolers' micronutrient intake.

Trends in the incidence of cancer of the corpus uteri in Connecticut, 1964-1979, in relation to consumption of exogenous estrogens.

The incidence of cancer of the uterine corpus diagnosed in the localized 1964 and 1969. During the next six years, however, it increased substantially, reaching a peak in 1975, followed by an irregular decline through 1979. Women aged 45-64 years showed both the largest increase and the sharpest decline. The incidence of tumors diagnosed with regional or distant spread has been rising slightly but consistently through the period 1970-1979; this upward trend is statistically significant (p less than 0.01). Rates corrected for hysterectomized women not truly at risk are 40-50% higher than uncorrected rates but trends are the same. Explanations which are considered are changes in diagnostic practices and changes in risk factor prevalence. The use of noncontraceptive oral estrogens, a well documented risk factor for endometrial cancer, increased between 1964 and 1975 and then declined sharply through 1979 in the United States. The importance of these compounds in explaining the observed incidence trends is considered in terms of the major time- and stage-specific features of the exogenous estrogen-endometrial cancer association reported in the case-control studies.
