The public health role in the primary prevention of diabetes: recommendations from the chronic disease directors' project.

AIM: The article reports on the recommendations from the Diabetes Primary Prevention Project that was initiated and funded by the Division of Diabetes Translation, Centers for Disease Control and Prevention, and developed by the National Association of Chronic Disease Directors. METHOD: Essential components of statewide programs are delineated for effective interventions for diabetes primary prevention. The recommendations were derived from a structured process that is detailed on the basis of a cross-comparison of state-level diabetes prevention initiatives in six states where such programs were most developed. RESULTS: The recommendations focus on state-level partnerships, statewide program planning, required resources, policies, benchmarks for progress, and data collection. CONCLUSION: Illustrations are provided regarding how the project influenced the six participating states in further developing their programs for the primary prevention of diabetes.

Conducting environmental assessments for physical activity: determining traffic volume in walkability audits in two West Virginia communities.

BACKGROUND: In this article, we examine the possibility of reducing time to conduct traffic volume audits through (1) reducing time for manual traffic counting and (2) using Department of Transportation (DOT) information. METHODS: In audits of 824 road segments in 2 West Virginia (WV) communities, manual traffic counts were recorded for 1, 2, and 5 min in duration. Annual Average Daily Traffic (AADT) was calculated from counts. Available AADT from DOT was also collected. Percent agreement and a weighted kappa were calculated between 5-min count and 1- and 2-min count AADT categories and between 5-min count and DOT AADT categories. RESULTS: One- and 2-min counts produced identical AADT categories as 5-min counts in 93.4% and 95.0% of segments, respectively. Weighted kappa was 0.79 (95% CI = 0.74-0.85) and 0.85 (95% CI = 0.80-0.89), respectively. Forty-two segments (5.1%) had DOT data. CONCLUSIONS: DOT AADT was available for a small percentage of road segments assessed. The high agreement between AADT categories produced by 1- and 2-min counts and 5-min counts makes it reasonable to consider using 1- or 2-min manual traffic counts if time or staffing constraints make it necessary. Possible generalizability of this methodology to other communities, particularly larger urban and suburban areas, will require further research.
