Relative Efficiency of Drag Fabrics for Collection of Blacklegged Tick (Acari: Ixodidae) Larvae, Nymphs, and Adults.

The blacklegged tick (Ixodes scapularis Say) vectors several bacterial, protozoan, and viral human pathogens. The known distribution, abundance, and phenology of I. scapularis within its estimated range are incomplete. This gap in knowledge is problematic because these factors are important for determining acarological risk of exposure to infected ticks. Consequently, enhanced surveillance of I. scapularis is being promoted and supported in the United States. Although the most common method for collecting I. scapularis is by dragging a sturdy cloth along the ground, there are no published empirical data showing which drag fabric is most effective. We used a randomized block design to directly compare the relative efficiencies of canvas, corduroy, and flannel drags for the collection of larval, nymphal, and adult I. scapularis. Overall, flannel was the most effective fabric and canvas was the least effective. Significantly more adults were collected on flannel than on canvas or corduroy, and the same number of nymphs was collected on flannel and corduroy. Significantly more larvae were collected on flannel than on canvas, but one-third of larvae could not be removed from the former fabric by lint-rolling, and handpicking was difficult. Our findings support the use of flannel drags to maximize sampling effort for collection of I. scapularis, especially adults to determine the presence of ticks and tick-borne pathogens when density and infection prevalence are low, with the caveat that detection and removal of larvae are time-consuming.

Barriers to resistance training among college-aged women.

OBJECTIVE: To examine resistance training (RT) barriers among college-aged women. PARTICIPANTS: Female college students (n = 223) from a Midwestern university. METHODS: Data were collected in September 2014. Participants completed a survey assessing demographics, current and past RT habits, and barriers to resistance training. Descriptive statistics were used to examine barrier agreement. Differences between current and past RT participation, residency, and class standing were analyzed. RESULTS: A majority of participants were Caucasian (78.9%) and, on average, 19.7 ± 1.5 years of age; 52% participated in RT and 46.6% met RT recommendations. Women who did not report current RT participation reported significantly higher mean agreement with all barriers, compared to those who do RT. Highest agreement was observed within socially based barriers. CONCLUSION: A majority of college-aged women are not meeting RT recommendations. Providing educational programs and avenues for finding same-sex RT partners may be most beneficial for overcoming common RT barriers.

Development and Testing of the Church Environment Audit Tool.

OBJECTIVES: In this paper, we describe development and reliability testing of a novel tool to evaluate the physical environment of faith-based settings pertaining to opportunities for physical activity (PA) and healthy eating (HE). METHODS: Tool development was a multistage process including a review of similar tools, stakeholder review, expert feedback, and pilot testing. Final tool sections included indoor opportunities for PA, outdoor opportunities for PA, food preparation equipment, kitchen type, food for purchase, beverages for purchase, and media. Two independent audits were completed at 54 churches. Interrater reliability (IRR) was determined with Kappa and percent agreement. RESULTS: Of 218 items, 102 were assessed for IRR and 116 could not be assessed because they were not present at enough churches. Percent agreement for all 102 items was over 80%. For 42 items, the sample was too homogeneous to assess Kappa. Forty-six of the remaining items had Kappas greater than 0.60 (25 items 0.80-1.00; 21 items 0.60-0.79), indicating substantial to almost perfect agreement. CONCLUSIONS: The tool proved reliable and efficient for assessing church environments and identifying potential intervention points. Future work can focus on applications within faith-based partnerships to understand how church environments influence diverse health outcomes.

Effects of a Group-Based Behavioral Intervention on Dietary Behaviors in Older Adults.

OBJECTIVE: The aim of this study is to examine the effects of a 12-week, behavioral nutrition intervention on dietary behaviors. METHOD: Inactive older adults ( N = 50) were randomized to a 12-week, behavioral nutrition or physical activity intervention, delivered in a group-based format. Questionnaires assessed fruit and vegetable (FV) consumption, and fat- and fiber-related behaviors at baseline and postintervention. Height and weight were measured. Repeated-measures ANOVAs examined changes in dietary behaviors over time between groups, controlling for age, gender, and education. RESULTS: Participants averaged 64.1 ± 8.4 years of age and had a body mass index (BMI) of 33.3 ± 7.5 kg/m2. Group × Time interactions were significant for FV consumption ( p = .003), and fat- ( p = .02) and fiber-related ( p = .008) behaviors at 12 weeks. At 12 weeks, dietary behaviors improved significantly in the nutrition but not in the physical activity group. Effect sizes were medium to large. DISCUSSION: A 12-week, behavioral nutrition intervention improved dietary behaviors. Behavioral interventions may be a low-cost way to improve dietary behaviors among older adults, potentially affecting population health significantly.
