The ultimate ability to measure and adjust for potential confounding factors is not certain, nor is it clear how the information from the health survey would be applied to the study cohorts. A detailed written analysis plan specifying primary exposure metrics and key confounders should be prepared in advance of the analysis and should consider alternative approaches to controlling confounders. It is not clear that the cancer-incidence study or the health survey would be successful; success in the former would be contingent on the cooperation of many cancer registries, and success of the latter on generating an adequate response. ATSDR has prepared a report on the feasibility of conducting epidemiologic studies to address exposures that occurred at Camp Lejeune Bove and Ruckart The sensitivity of results to potential confounders should be examined more thoroughly. Fourth, as previously noted, the quality of exposure data would remain uncertain for the same reasons noted above in connection with the completed and current studies. Cut points will be determined from the contaminant-concentration distributions. Both analyses focused on pregnancy outcomes regarding live-born infants, including mean birth weight, small for gestational age SGA , and preterm delivery. Historical reconstruction of the water-distribution system serving the Dover Township area, New Jersey: Because all state cancer registries have data available from on, cancer incidences in the Camp Lejeune and Camp Pendleton cohorts will be compared with national incidences for the period Currently we do not know which mothers received the water with VOCs.

The year is the starting point because that year North Carolina began computerizing its birth records. Two year trial period may be required. Both studies assumed that all mothers who resided in family housing in the Holcomb Boulevard system service area from through were unexposed. However, the panel concluded that it might be feasible to conduct a study of mortality outcomes and a study of cancer incidence. One major problem is that the number of people available for the study may be too small to generate statistically meaningful results related to rare outcomes of greatest interest such as kidney cancer. The verification process will continue until the diagnoses for the potential cases are either confirmed or not confirmed. ATSDR also proposes to compare those exposed to contaminated drinking water at Camp Lejeune with those unexposed at Camp Pendleton to minimize bias due to the healthy-veteran effect caused by differences in underlying mortality between veterans and the general public Bove and Ruckart Experience refers to paid and unpaid experience, including volunteer work done through National Service programs e. A draft of the protocol for the study has been completed, and ATSDR will be seeking input on the draft protocol from concerned citizens as well as scientists outside the government. The authors concluded that there was no association between PCE exposure and mean birth weight or preterm birth and that there was a weak association between PCE exposure and SGA in all groups. Second, the contaminant exposure and its variation over time are impossible to quantify accurately. The planned secondary and sensitivity analyses should be discussed more fully in the analysis plan. Women with records showing a month and year of last menstrual period but missing information on the day had their day interpolated to For each of the three outcomes neural-tube defects, oral clefts, and childhood cancers , there is adequate power only for markedly increased odds ratios larger than 3. It could be argued that additional studies of the potential health effects from the historical contamination of drinking water at Camp Lejeune could help guide decisions on how to resolve the claims of former residents. Experience required:

Parents were asked if their children had had birth defects or childhood cancer. Women with records showing a month and year of last menstrual period but missing information on the day had their day interpolated to The key issue now is whether the diagnoses can be confirmed for most, if not all, of the potential cases of the birth defects and childhood cancers of interest that were identified by this survey. Salary includes applicable locality pay or Local Market Supplement. However, not all those variables were included in the analyses. We know that there were some highly contaminated wells for some periods, but their operations were cycled with those of uncontaminated wells, so exposure to water contaminants was intermittent and cannot be determined on an individual basis or for time frames of weeks as required to assess the occurrence of reproductive health end points. Review of data and modeling efforts pertaining to exposure provided clear documentation that contaminants were present but provided little basis for suggesting that exposures of the population can be reconstructed with much precision. Because was the first year that birth certificates were computerized in the state, the year was chosen as the start of the study period in both the previous SGA study and the current survey. As a practice, the establishment disposed of waste solvent by draining it into a septic tank or by releasing it onto the ground. Careful attention should be paid to confounding, given the associations between residence and indicators of risk. Finally, the longstanding controversy over this episode is apparent, and some question the objectivity of the Marine Corps in generating valid, objectively interpreted scientific data on the topic. Given the inherent limitations of birth-certificate data, sensitivity analyses to address gestational-age misclassification, subgroup analyses, and confounding should be incorporated. For this job, you may qualify if your education meets the definitions below: The fourth and final step of the process is to conduct a case-control analysis that incorporates water-system modeling; that work is under way. The year was chosen as the end date of the study because the contaminated wells were shut down that year. Beyond its obvious impact on interpretation of the exposure-duration analyses, the effect of a selection approach based on location at the time of delivery is unknown.

Study population. Preterm birth was defined as a live birth occurring before completion of 37 weeks of gestation. A similar approach will be used for the epidemiologic study at Camp Lejeune. Infants whose mothers were transferred or moved away from Camp Lejeune before giving birth were not included. Consequently, those studies provide little information to assess directly whether the population exposed to water contaminants has suffered adverse health effects of them. The financial cost is also a key consideration in that studies that require generating large volumes of new data through individual contact and advanced water modeling are expensive and time-consuming. Finally, the agency proposed to consider lagging exposures in the analyses to account for a latent period. In analyses, duration of exposure was categorized as never, weeks, weeks, weeks, over 20 weeks and less than the entire pregnancy, the entire pregnancy and less than 1 year before the last menstrual period, and the entire pregnancy and at least 1 year before the last menstrual period. Because individual-level information on potential confounders is not available in the computerized databases used to identify study subjects, ATSDR proposes two approaches to consider potential confounders. Gestational age was calculated from the date of the last menstrual period reported on the birth certificate. Because there is interest in multiple exposure periods for various durations before, during, and after pregnancy , in different approaches to estimating exposure, and in different exposure categories, it is necessary to distinguish the primary exposure metric such as peak exposure from those to be evaluated in secondary and sensitivity analyses. Permission to gain access to medical records will be requested from those reporting cancer diagnoses. The results of the model will enable the epidemiologic study to establish whether the mothers of the children with birth defects or cancers of interest were more likely to have been exposed during their pregnancy to the drinking water contaminants than were the mothers of the controls. As a practice, the establishment disposed of waste solvent by draining it into a septic tank or by releasing it onto the ground. Of the 29 reported childhood leukemia or non-Hodgkin lymphoma cases, 13 were confirmed 11 leukemia and two non-Hodgkin lymphoma , eight were ruled out, one had no medical records for confirmation, four were ineligible, and the parents of three potential cases refused to participate. If the parent stated that the eligible child had been diagnosed by a physician as having a birth defect or childhood cancer, then the parent was asked for the specific type of birth defect or cancer. If the Navy-Marine Corps health survey is successful, the cancer-incidence study would also include participants in the survey. Please follow all instructions carefully when applying, errors or omissions may affect your eligibility. Review and Evaluation ATSDR proposed to conduct morbidity and mortality studies that would address some of but not all the questions that have been raised by the affected community. However, there are concerns about the comparability of the women at Camp Lejeune, who include spouses of workers and women identified because of having given birth, compared with those identified at Camp Pendleton. One sample taken in before the contaminated wells were shut down indicated a PCE level of ppb was found. The participation rate for Group 1 children was That issue would need to be addressed from the outset in framing the question, the mechanism of funding, the selection of the researchers, the conduct of the study, and the interpretation, evaluation, and dissemination of results. Survey Questionnaire The survey questionnaire was administered to the parent most often the mother using a computer-assisted telephone interviewing CATI system, and answers were entered directly into the computer. Births in the long-term TCE-exposed group were to mothers living in housing ordinarily served by the Hadnot Point water-distribution system. Candidates in this category meet the minimum experience requirements for the announced position.

In subgroup analyses, Sonnenfeld et al. The number of pregnancies that occurred at base housing during the study period and that resulted in live births to mothers who lived off the base at the time of delivery is unknown. Those studies have not distinguished and are unlikely to be able to distinguish between an absence of adverse effects and the presence of modest effects that fall below the limits of what can be identified in light of exposure misclassification and low statistical power. However, because of information about how these chemicals might affect a fetus or child, the levels of the contaminants in the drinking water, and the findings from previous studies conducted in other states, the PHA recommended that an epidemiologic study be performed at Camp Lejeune. The Dover Township drinking water system model was based on field-data collection of the present-day system operations and a historical reconstruction of fate and transport of contaminants within the water system, using historical information available from the water company. These records are now under review. ATSDR proposes a two-stage approach, using the survey data to estimate the effects of confounding with reference to the cohort as a whole. These estimates were then applied to the residences of the cases and controls. Before , the Holcomb area was served by the Hadnot Point water distribution system. In particular, accurate estimates of the date of the last menstrual period are critical for defining SGA and preterm birth. ATSDR discussed the possibility of missed cancers in the incidence study due to incomplete coverage of the study period by the individual state cancer registries. That population did not include births to mothers who resided on the base during pregnancy but were no longer residents of Onslow County at the time of delivery. The high levels of contamination found in the drinking water at Camp Lejeune during testing in — The likelihood that the drinking water was contaminated in prior years The scientific literature on the adverse health conditions of interest, and The potential number of confirmed cases of these conditions of interest.

The authors reported no consistent patterns in the associations between PCE exposure and mean birth weight, preterm birth, or SGA by duration of exposure. Bookshelf ID: Duration-of-exposure analyses excluded births that occurred after exposure ended in No risk of any of the outcomes was found in the temporarily exposed population with a maximum exposure duration of 12 days. The health outcomes of interest vary greatly in frequency of occurrence. Currently we do not know which mothers received the water with VOCs. The much smaller population of TCE-exposed births was analyzed with stratification by residence. Outcome variables were based on information included on birth certificates, and there are known limitations in the quality of some items Wingate et al. The residents of Camp Lejeune potentially exposed to the contaminated water supplies of concern need to be enumerated for study, with inclusion of exposed people and comparable unexposed people identified from elsewhere on the base, from periods beyond the years of contamination, or from other military bases. That would allow inclusion of monthly estimates of water contamination from the water-distribution system in individual-level exposure assessment. Experience refers to paid and unpaid experience, including volunteer work done through National Service programs e. Instead, they provided only descriptions of the birth defects e. The implications of the results of subgroup analyses are unclear. In spite of the reported difference, the birth-weight results were said to show no association, because the magnitude of the difference was viewed as clinically negligible. For example, it was unclear whether ATSDR would assess the effect of cumulative exposure or of peak exposure. Potential confounders. As a practice, the establishment disposed of waste solvent by draining it into a septic tank or by releasing it onto the ground. ATSDR initially planned to evaluate fetal deaths, also, but that plan was abandoned because of the small number 83 of fetal deaths identified with the computerized state database and because the cause of fetal death was missing from death certificates in most cases ATSDR ATSDR recognized the potential for bias in the assessment of exposures because of uncertainties in identifying locations on the base where cohort members were stationed and because of possible exposure to drinking-water contaminants at other than primary residences or work locations. Please follow all instructions carefully when applying, errors or omissions may affect your eligibility. Finally, the longstanding controversy over this episode is apparent, and some question the objectivity of the Marine Corps in generating valid, objectively interpreted scientific data on the topic. Water use and consumption will be incorporated into the exposure metrics. Sci Total Environ ; Candidates in this category possess exceptional skills and experience to exceed well above the minimum requirements for the announced position. Third, the health survey would include only active-duty personnel and civilians who lived on the base after , not those who were present and exposed before then.

All-Cause Mortality Study The purpose of the mortality study is to evaluate all causes of death in the three cohorts—Camp Lejeune military, Camp Lejeune civilian, and Camp Pendleton military. Reanalyses should include development of a detailed written analysis plan for example, Sheppard For example, the survey would enhance the collection of relevant covariates and expand the potential scope of nonfatal disease and disability beyond what can be addressed in a typical mortality study or in a cancer registry. To compute the percentage of the requirements, divide your total months of qualifying experience by The CHAMPS database can also be used to identify and confirm diseases occurring in marines on active duty from on. ATSDR decided on children born to women who were pregnant with them while living on the base during — In the course of exposure reconstruction of the Tarawa Terrace system, it was learned that the Holcomb Boulevard plant came on line in June and that before then the housing now served by Holcomb Boulevard was served by the Hadnot Point water-supply system. To the extent that scientifically valid epidemiologic research has been conducted directly on Camp Lejeune residents, extrapolation is unnecessary. The high participation rate supports the likelihood that most birth defects and childhood cancers among the eligible children have been identified. The PHA for Camp Lejeune determined that exposures to the levels of drinking water contaminants from the dry-cleaning establishment and the on-base sources would most likely not result in adverse health effects to adults ATSDR Those are reasonable strategies but are of unknown feasibility. For instance, nearly all infants who were exposed only during the first trimester were excluded. Relative to the overall effort expended thus far, the committee recognizes the need for completion of this study. The year is the starting point because that year North Carolina began computerizing its birth records.

Trenton, New Jersey: Consequently, those studies provide little information to assess directly whether the population exposed to water contaminants has suffered adverse health effects of them. Parents were asked if the child had had a birth defect or had developed a childhood cancer. A case-control study of childhood leukemia in Woburn, Massachusetts: The final step will be to conduct a full study. The birth defects of interest were spina bifida and anencephaly, which are neural tube defects of the central nervous system oral clefts, that is, cleft lip and cleft palate. To qualify based on your work experience, your resume must describe at least one year of experience which prepared you to do the work in this job. Experience required: In addition, communications from the USMC in the form of memos, e-mails, and media information releases prompted some parents of eligible children or the eligible children themselves who were now adults to contact ATSDR or the USMC for information on the survey. Historical reconstruction of the water-distribution system serving the Dover Township area, New Jersey: The USMC also sent an e-mail message to current marines asking if they had been conceived or carried in utero during the study period while their mothers lived in Camp Lejeune on-base housing. First, the statistical power for evaluating relevant outcomes appears to be low and incompletely addressed in the feasibility study. The number of pregnancies that occurred at base housing during the study period and that resulted in live births to mothers who lived off the base at the time of delivery is unknown. The analyses assumed delivery of contaminated water via the water-distribution system through February ATSDR ; Sonnenfeld et al. That information will be used to adjust for confounding in the analyses of the entire study population. Cause-specific mortality in the cohorts would be compared with national rates by using standardized mortality ratios and standardized mortality ORs. Review of data and modeling efforts pertaining to exposure provided clear documentation that contaminants were present but provided little basis for suggesting that exposures of the population can be reconstructed with much precision. The survey, conducted from September to January , built on the database initially constructed for the two case-control studies of preterm birth and fetal growth ATSDR ; Sonnenfeld et al. For each of the three outcomes neural-tube defects, oral clefts, and childhood cancers , there is adequate power only for markedly increased odds ratios larger than 3. Eligible children were identified in two ways. Finally, the agency proposed to consider lagging exposures in the analyses to account for a latent period. Decisions regarding the appropriate policy response to health concerns about exposure to contaminated water at Camp Lejeune should not be delayed or await the results of epidemiologic studies that are in progress or planned inasmuch as those studies are unlikely to provide definitive information on potential health effects. A childhood cancer was defined as a cancer diagnosed before the age of 20 years for those children born during Nevertheless, the committee has several concerns about the health survey as a source of scientifically useful information for assessing the impact of water-supply contamination at Camp Lejeune.

The primary hypotheses concern the association between drinking TCE- or PCE-contaminated water during the first trimester and specific birth defects and the association between drinking TCE- or PCE-contaminated water during pregnancy and childhood cancers. Two published analyses resulted from that effort: Only the full study can establish whether VOC-tainted drinking water may cause the childhood health problems being studied. As indicated in Chapter 2 , exposure estimates based on water-system modeling require a number of assumptions, and the validity of many of the assumptions is impossible to evaluate in light of the historical measurement data. Additional information Selection is subject to restrictions resulting from Department of Defense referral system for displaced employees. The cancer-incidence study would also have greater power to detect associations with a broader array of cancers of interest such as kidney, non-Hodgkin lymphoma, and leukemia and would eliminate potential effects of differential survival. Since residence or workplace on the solitary is a primary exhibit of carriage and may be knowledgeable to extravaganza, main, or job duty, which themselves may be differences tarwaa disease risk, they would enjoy to be measured and very for in the solitary.

As it noted, there should be no bias in the internal comparisons, because missing cases are unlikely to be associated with exposure status. Survey Questionnaire The survey questionnaire was administered to the parent most often the mother using a computer-assisted telephone interviewing CATI system, and answers were entered directly into the computer.
