First Followup Examination Results written by and published by . This book was released on 1987 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report represents the results of the health assessment of the 1, 016 Ranch Hands and the 1,293 Comparisons who participated in the 1985 followup examination of the Air Force Health Study. The purpose of the study is to determine whether long-term health effects exist and can be attributed to occupational exposure to herbicides. The result show a subtle but consistent narrowing of medical differences between the two groups since the Baseline study in 1982; however, the Ranch Hands continue to manifest slightly more minor adverse health conditions than the Comparisons. Continued surveillance of these groups is indicated. The report concludes that there is not sufficient evidence to implicate a causal relationship between herbicide exposure and adverse health in the Ranch Hand group. Keywords: Health surveys; Epidemiologic investigation; Phenoxy herbicides; Herbicide orange; Dioxin; Air Force health study, Morbidity.

Volume I: 1997 Follow-up Examination Results written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes results from the Air Force Health Study (AFHS). The AFHS is an epidemiological study to determine whether adverse health effects attributable to exposure to herbicides exist in veterans of Operation Ranch Hand Operation. Ranch Hand was the unit responsible for the aerial spraying of herbicides, including Herbicide Orange, in Vietnam from 1961 to 1971. A Comparison cohort comprised Air Force veterans who served in Southeast Asia during the same time period that the Ranch Hand unit was active and who were not involved with spraying herbicides. The summarized data were collected during a physical examination administered between May 1997 and April l998. Of 1,149 eligible Ranch Hands, 870 (73.7%) participated and of 1,761 eligible Comparisons, 1,151(71.0%) participated. Statistical analyses assessed differences between Ranch Hands and Comparisons and associations between health-related endpoints and extrapolated initial dioxin, dioxin exposure category (Comparisons, background Ranch Hands, low Ranch Hands, high Ranch Hands), and dioxin measured in 1987. The study has insufficient statistical power to assess increases in the risk of rare diseases, such as soft tissue sarcoma. Diabetes and cardiovascular abnormalities represent the most important dioxin related health problems seen. From a public health perspective, these two areas demand the greatest attention.

Book excerpt: This report summarizes results from the Air Force Health Study (AFHS) 2002 follow-up physical examination. The AFHS was undertaken to determine whether adverse health effects attributable to exposure to herbicides existed in veterans of Operation Ranch Hand. The men assigned to Operation Ranch Hand flew aerial herbicide spray missions in Vietnam from 1962 to 1971. A comparison cohort comprised Air Force veterans who served in Southeast Asia during the same time period and who were not involved with spraying herbicides. A total of 1,951 veterans participated in the 2002 physical examination 777 Ranch Hands & 1,174 Comparisons. Statistical analyses assessed differences between Ranch Hands & Comparisons & associations between health- related endpoints & extrapolated initial dioxin, dioxin category, and dioxin measured in 1987. The study has insufficient statistical power to assess increases in the risk of rare diseases. Consistent with past AFHS reports, current results indicate a significant & clinically meaningful adverse relation between type 2 diabetes & exposure to dioxin.

Baseline Morbidity Study Results written by George D. Lathrop and published by . This book was released on 1984 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1979 the United States Air Force (USAF) made the commitment to Congress and to the White House to conduct an epidemiologic study of the possible health effects from chemical exposure in Air Force personnel who conducted aerial herbicide dissemination missions in Vietnam (Operation RANCH HAND). The purpose of this epidemiologic investigation is to determine whether long-term health effects exist and can be attributed to occupational exposure to herbicides. This study uses a matched cohort design in a noncurrent prospective setting, incorporating mortality, morbidity, and follow-up studies. This report presents the results of health information on 2706 Ranch Handers and comparison individuals obtained by questionnaire and 2269 Ranch Handers and comparison individuals undergoing an extensive physical examination. This baseline report concludes that there is insufficient evidence to support a cause and effect relationship between herbicide exposure and adverse health in the Ranch Hand group at this time. The study has disclosed numerous medical findings, mostly of a minor or undetermined nature, that require detailed follow-up. In full context, the baseline study results should be viewed as reassuring to the Ranch Handers and to their families at this time.

This book was released on 1995 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report represents the results from an epidemiologic study to determine whether adverse health effects attributable to Herbicide Orange exist in Vietnam veterans who participated in Operation Ranch Hand. Data were analyzed for 12 clinical areas. The analysis focused on group differences between the exposed (Ranch Hand) and unexposed (Comparison) cohorts, as well as on the association of each health-related endpoint with extrapolated initial and current serum dioxin levels. Findings in this report reveal a consistent relationship between dioxin and body fat that was initially noted in the analysis of the 1987 examination results. Cholesterol and the cholesterol to HDL ratio were found to be associated with current serum dioxin levels. Evidence for a possible association between glucose intolerance, impaired insulin production, and dioxin exposure was revealed, but cause and effect remain to be established. Also revealed was a significant association between selected peripheral pulses and dioxin exposure, and a significant difference in self-perceived health status between Ranch Hands and Comparisons (although possible due to bias). Other health endpoints revealed no consistent patterns within or across clinical areas that were suggestive of health detriment due to dioxin exposure.

Baseline Mortality Study Results written by and published by . This book was released on 1983 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1979 the United States Air Force (USAF) made the commitment to Congress and to the White House to conduct an epidemiologic study of the possible health effects from chemical exposure in Air Force personnel who conducted aerial herbicide dissemination missions in Vietnam (operation RANCH HAND). The purpose of this epidemiologic investigation is to determine whether long-term health effects exist and can be attributed to occupational exposure to herbicides. This study uses a matched cohort design in a nonconcurrent prospective setting, incorporating mortality, morbidity, and follow-up studies. The purpose of this report is to present the baseline mortality study results. As of December 31, 1982, 50 Ranch hand and 250 comparison subjects had died (certified on/before April 27, 1983). Data analysis showed that the mortality experience of the Ranch Hand group is nearly identical to that of this comparison group. However, this mortality report can in no way be regarded as conclusively negative since the study population may not yet have reached the latency period. Subsequent mortality reports will include additional analyses and will be updated annually for the next 20 years.

Book excerpt: In 1979 the United States Air Force (USAF) made the commitment to Congress and to the White House to conduct an epidemiologic study of the possible health effects from chemical exposure in Air Force personnel who conducted aerial herbicide dissemination missions in Vietnam (Operation RANCH HAND). The purpose of this epidemiologic investigation is to determine whether long-term health effects exist and can be attributed to occupational exposure to herbicides. This study uses a matched cohort design in a noncurrent prospective setting incorporating mortality, morbidity, and followup studies, Detailed computer searches of Air Force personnel records, with several cross-referencing techniques, have ensured total ascertainment of the RANCH HAND population. The unique circumstances of exposure in this population of 1264 individuals will permit a semiquantitative estimate of exposure. A comparison group will be formed from a population of 23,978 flight crew members and support personnel who were assigned to duty in Southeast Asia (SEA), but were not occupationally exposed to herbicides. These individuals will be matched to RANCH HAND personnel for the variables of age, type of job, and race. Since both the exposed subjects and their selected controls performed similar combat or combat-related jobs, many of the physical and psychophysiologic effects of combat stress and the SEA environment will also be equivalent in the two groups.
