Prevalence of SIDS risk factors: before and after the "Back to Sleep" campaign in North Dakota Caucasian and American Indian infants.

The objective of this study was to compare rates of infant sleeping position and other risk factors for sudden infant death syndrome from 1991 before the "Back to Sleep" campaign to rates in 1998 after the campaign. We used a cross-sectional risk factor prevalence study of risk factors for the years 1991 and 1998. In North Dakota the prevalence rates of prone sleeping declined 72% for American Indian infants and 62% for Caucasian infants. We were unable to identify a corresponding decline in SIDS in North Dakota for this time period. The relationship between sleeping position and SIDS may be more complex in rural and frontier settings and in American Indian populations than in urban and majority populations. The generalizability of this study is limited by the rural setting and small sample size. Longer term surveillance and additional reports from sites with pre "Back to Sleep" data as a baseline for both SIDS rates and sleeping position will be important to clarify the rate of prone sleeping position and SIDS.

Beverage consumption is not associated with changes in weight and body mass index among low-income preschool children in North Dakota.

OBJECTIVE: To examine prospectively the association between beverage consumption (fruit juice, fruit drinks, milk, soda, and diet soda) and changes in weight and body mass index among preschool children. DESIGN: A prospective cohort study that collected dietary, anthropometric, and sociodemographic data.Subjects/Setting The study population included 1,345 children age 2 to 5 years participating in the North Dakota Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on two visits between 6 to 12 months apart. Statistical analyses We performed linear regression analyses to examine whether beverage consumption was associated with annual change in weight and body mass index. Intakes were measured as continuous (oz/day) and we also dichotomized fruit juice, fruit drinks, and milk at high intakes. RESULTS: In multivariate regression analyses adjusted for age, sex, energy intake, change in height, and additional sociodemographic variables, weight change was not significantly related to intakes (per ounce) of fruit juice (beta=0.01 lb/year, 95% CI: -0.01 to 0.20, P=.28), fruit drinks (beta=-0.03 lb/year, 95% CI: -0.07 to 0.01, P=.28), milk (beta=0.00 lb/year, 95% CI: -0.02 to 0.02, P=.86), soda (beta=-0.00 lb/year, 95% CI: -0.08 to 0.08, P=.95), or diet soda (beta=0.01 lb/year, 95% CI: -0.11 to 0.13, P=.82). Findings remained null when we examined associations with body mass index and when fruit juice, fruit drinks, and milk were dichotomized at high intake levels in both analyses. CONCLUSIONS: Our study does not show an association between beverage consumption and changes in weight or body mass index in this population of low-income preschool children in North Dakota.

Bovine hydrocephalus in North Dakota: a survey and morphologic study.

A survey of hydrocephalus in cattle in North Dakota in 1975 and 1976 included 26 proven cases falling into categories comparable to that seen in the human situation. The largest group was hydrocephalus secondary to aqueductal stenosis with the second largest group being hydranencephaly. Other groups included the Dandy-Walker malformation, porencephaly and a miscellaneous group having a variety of central nervous system malformations. All cases were sporadic with no evidence to suggest a genetic basis. The similarity suggests that calves could serve as a useful model for the human situation.

Detection and characterization of Salmonella typhimurium from a dairy herd in North Dakota.

Nasal secretions, faecal samples and buffy coats were obtained from 102 cattle from a North Dakota dairy herd with a history of calf scours. Treated buffy coats, faecal samples and nasal secretions were inoculated into tetrathionate broth (TB), incubated at 37 degrees C overnight, and plated onto brilliant green agar medium with novobiocin (BGAN). The TB was left at room temperature for 5 days and then used to inoculate fresh TB. The fresh TB was incubated at 37 degrees C over night and plated onto BGAN medium. All the plates were incubated at 37 degrees C over night and observed for Salmonella-like growth. Suspect colonies were further tested and Salmonella isolates were serotyped by the National Veterinary Services laboratory. Twenty-two of the 36 calves sampled harboured S. typhimurium in their faeces, but no samples from cows were positive. No Salmonella were isolated from the buffy coats, but 4 calves were shown to have Salmonella in their nasal secretions. Extended enrichment of the faecal cultures in TB resulted in a significant increase in Salmonella isolations, although 2 samples were positive following the initial enrichment period and not after secondary enrichment. The typical Salmonella isolate detected from this herd contained a transmissible R-plasmid encoding resistance to tetracycline, kanamycin, sulphisoxazole and ampicillin. This study confirmed that delayed secondary enrichment in TB is superior to primary enrichment for detection of Salmonella from cattle.

Concentration of mercury in animal products and soils of North Dakota.

Total mercury (Hg) was determined in milk, eggs, beef, pork, human head hair, soil and water obtained from four geographical areas of North Dakota. The sampling areas were selected on the basis of differences in prevalent agricultural practices, climate and topography. Statewide average Hg concentrations in ppb were milk, 0.8; eggs, 12; beef muscle, 5; beef liver, 10; pork muscle, 11; pork liver, 15; head hair, 1708; soil, 30; rainwater and well water, less than one. There were no significant differences observed among areas in Hg content of any substance sampled except beef muscle. Beef muscle obtained from areas 2 and 4 contained significantly (P less than or equal to 0.05) higher levels of Hg than beef muscle from the other two areas. However, the magnitudes of differences were small (4 to 6 ppb). Considerable variation among individual beef and swine were noted but only six beef of 453 sampled and three swine of 156 sampled had tissue Hg exceeding 50 ppb. Appreciable variation was observed in Hg in eggs with respect to farms within an area, eggs from the same farm, and sampling times within a year. Few eggs sampled contained more than 50 ppb. Significantly (P less than or equal to 0.01) higher levels of Hg were found in head hair of women as compared with men and relatively large differences among individuals were observed. Average Hg in hair was generally low irrespective of sex of donor or area of the state as compared with data given in the literature. Soil Hg levels were consistently low in all areas of the state, and no relationship between cropping practices and soil Hg was detected.

Studies on sylvatic echinococcosis. V. Factors influencing prevalence of Echinococcus multilocularis Leuckart 1863, in red foxes from North Dakota, 1965--1972.

A total of 1,153 red foxes, Vulpes vulpes, was examined for strobilae of Echinococcus multilocularis from 2 geographic regions in North Dakota during 1965 through 1972. Echinococcus multilocularis was found in 184 (16%) of these foxes. The data including date and location of collection, age and sex of the host, and presence or absence of the cestode were used to assess the relative influence of collection interval (sampling period), climatic season, geographic location, and age and sex of the host on the prevalence of the adult cestode. The rate of infection varied significantly with collection interval, which was probably attributable to annual changes in the overall environment. Seasonally, the highest prevalences were observed during summer (32.4%) followed by spring (25.3%), autumn (13.7%) and winter (6.4%). Differences in prevalence between adult and juvenile foxes and that between male and female foxes were not significant. A 3-factor analysis of variance showed the order of importance of the significant variables to be collection interval, season, and the interaction of collection interval and season. A 4-factor ANOVA, which in addition to the above variables included geographic location, showed that the collection interval-location interaction had significant effects on prevalence. Also, evidence is presented that suggests that density of the definitive host may in part be responsible for annual fluctuation in prevalence.

Diabetes and its complications among selected tribes in North Dakota, South Dakota, and Nebraska.

OBJECTIVE: To determine the prevalence and incidence rates of diabetes and two specific complications for selected American-Indian tribes in North Dakota, South Dakota, and Nebraska. RESEARCH DESIGN AND METHODS: A descriptive epidemiological study was conducted using ambulatory care data during 1987 for prevalence and diabetes registries and complication case reporting during 1988 from IHS facilities on reservations in these states. RESULTS: The Winnebago and Omaha tribes had the highest age-adjusted diabetes rates, with prevalence 8.8 times and incidence 7.7 times the respective U.S. rates. The diabetes prevalence rate of combined data for the Sioux was 3.7 times the U.S. rate. Among Sioux Indians, the age-adjusted incidence rate for ESRD was 4.8 times the American-Indian/Alaska-Native rate and 13.4 times the rate for U.S. whites. The proportion of new diabetes-related ESRD (86%) was almost 3 times greater than the general U.S. population rate (30%). Also, among the Sioux, the age-adjusted incidence rate for LEA (86.7/10,000 diabetic population) was 1.5 times higher than the U.S. rate; the proportion of diabetes-related LEA (84%) was 1.8 times higher than the general U.S. population rate (45%). CONCLUSIONS: The age-adjusted rates of diabetes and certain complications among these Northern Plains tribes are greater than the U.S. rates. Improved health services to detect and monitor diabetes and its complications and community-based prevention activities directed at the epidemic of diabetes among the various Indian tribes are urgently needed.

Prevalence of psychoactive drug use among North Dakota group home residents.

To determine the prevalence of psychoactive medication usage among persons with mental retardation residing in community settings in the state of North Dakota, we sent a questionnaire to all group homes serving persons with developmental disabilities. The return rate was 97%. Psychoactive medications were used by 37% of residents represented. Results were discussed in relation to previous studies that have primarily involved institutionalized populations.

Motorcycle-related trauma and helmet usage in North Dakota.

A descriptive epidemiologic study utilizing a multi-disciplinary reporting format was undertaken to assess the impact of helmet usage on motorcycle trauma in North Dakota from 1977 through 1980. This approach yielded an 82.6% reporting increase compared to previous data collection techniques. More than 60% of the 2,934 crashes involved unhelmeted cyclists. Two-thirds of all crashes resulted in injury, with head, neck, and face (HNF) trauma accounting for 21.4% of all lesions. Compared to their helmeted counterparts, helmetless riders suffered HNF trauma 2.30 times as often, and were 3.19 times as susceptible to fatal injuries. the number of injuries and the severity of trauma were significantly higher (P = .01) for those individuals not wearing helmets. A substantial decline in usage occurred in those under 18 years of age, despite the legal requirement that this group wear protective headgear.

Survey of North Dakota sunflower seeds for aflatoxin.

In a survey of oil-type sunflower seeds, 89 samples were collected from 32 storage bins in 10 counties of North Dakota in 1979. None of these survey samples exceeded the 20 ppb Food and Drug Administration aflatoxin guideline. Four research samples, from 2 grossly spoiled storages, contained 100-1100 ppb aflatoxin B1. This research is believed to be the first to document natural aflatoxin contamination in sunflower seeds.

Western equine encephalitis in avian populations in North Dakota, 1975.

The involvement of wild birds in western equine encephalitis (WEE) and St. Louis encephalitis (SLE) virus activity in the Red River valley area of North Dakota (USA) during a WEE epidemic was investigated in August 1975. Free-ranging birds were captured with mist nets and nestlings by hand. Virologic and serologic results indicated that a similar rate of WEE virus activity occurred throughout Richland County and between permanent and summer resident birds. The rate of SLE virus activity in the birds of Richland County was lower than for WEE virus, but the SLE antibody prevalence was greater in rural areas than within urban locations. Seven of the nine WEE virus isolations were from nestling birds of four different species; the remaining two from adults of two different species. Overall prevalence of neutralizing (N) antibody against WEE virus was 5% in nestling and 14% in adult birds but was the opposite for N antibody against SLE virus, 17% in nestling and 5% in adult birds. Differences between the two viruses in the presence and persistence of maternal N antibody or differential mortality in nestling birds may have caused the disparity in antibody prevalences.

Salt toxicosis in waterfowl in North Dakota.

About 150 waterfowl died and another 250 became weak and lethargic from suspected salt poisoning after using White Lake, a highly saline lake in Mountrail County, North Dakota. Frigid temperatures made fresh water unavailable, forcing the birds to ingest the saline waters with resultant toxic effects. Sick birds recovered when removed from the salt water and released into fresh water marshes. Brain sodium levels were higher in dead geese submitted for necropsy than in controls.

Population and movement characteristics of radio-collared striped skunks in North Dakota during an epizootic of rabies.

We observed a total of 102 striped skunks (Mephitis mephitis) from March to July of both 1991 and 1992 in Stutsman County, North Dakota (USA) during an experiment with food supplementation. Twenty-three apparently healthy skunks in 1991 and 56 in 1992 were equipped with radio-collars. In 1991, one of the 23 was tested and found to be rabid. In 1992, 50 of 56 were tested; 35 (70%) were rabid. Of skunks with ages estimated, 19 (66%) of 29 were first year animals in 1991 compared with nine (22%) of 41 first year animals in 1992. All 18 females captured in 1991 were pregnant or parous compared with 21 (60%) of 35 in 1992. The estimated survival rate of skunks was 0.85 during April to June 1991, but only 0.17 during April to July 1992. In 1992, the survival rate of first year skunks was 0.08, compared with 0.35 for older animals. Eleven (31%) of 36 skunks found dead of rabies or in late clinical stage were located below ground. We detected no differences in 1992 between healthy and rabid skunks in estimated mean (+/- SE) rate of travel (232 +/- 14 m/hr), distance traveled (2,047 +/- 141 m/night), or home range size (1.6 +/- 0.4 km2) during half-month periods from April through June. Among rabid skunks, mean rate of travel tended to decrease from 298 +/- 48 m/hr during the 14 days preceding the clinical period of rabies (pre-clinical) to 174 +/- 48 m/hr during the clinical period of rabies (14 days immediately before death). Similar decrease occurred in distance traveled in a night (2,318 +/- 281 m, pre-clinical; 1,497 +/- 281 m, clinical). Mean home range size of males (2.8 +/- 0.4) was greater than of females (1.2 +/- 0.4) during the pre-clinical period, but during the clinical period home range sizes of males (1.8 +/- 0.4) and females (1.8 +/- 0.4) were similar. Mean home range size of females did not differ between pre-clinical (1.2 +/- 0.4) and clinical (1.8 +/- 0.4) periods (P = 0.22). Deaths of skunks from rabies in 1992 tended to be more spatially clumped than expected had they been random, mostly due to deaths detected before 8 May. We detected no correlation between locations of animals found dead of rabies and dates of death.

Cestode in North Dakota: echinococcus in field mice.

Field mice (Microtus pennsylvanicus and Peromyscus maniculatus) are naturally infected with Echinococcus multilocularis. Thus, the sylvatic cycle (fox to field mice to fox) has been established in North Dakota. This cestode is expected to extend its range to other agricultural regions of the continental United States where similar conditions favorable for the completion of its life cycle exist.
