The impact of climate-related extreme events on public health workforce and infrastructure – how can we be better prepared?

The Intergovernmental Panel on Climate Change’s fifth assessment report1 states with confidence that human induced climate change is occurring and that temperatures will continue to rise, even if CO2 emissions were to stop forthwith. The report also acknowledges that climate-related extreme events are increasing in frequency, severity and duration; particularly heavy rainfall events, intensification of cyclones, increases in tidal surge and fires. This poses the question: “Are we prepared?” This is question that public health authorities will need to face but, as health systems are increasingly stressed due to limited resources, increased demand and workforce shortages, being prepared becomes even more challenging. Extreme events place an additional burden on health systems already under pressure due to increased demand for health care services, and as public health resources are offset against the demands in the acute care sector. (For the purposes of this paper, public health services refer to those health and related services that seek to prevent disease and promote health.) The impact on often already overstretched public health services may not be recognised, and additional resourcing and support may not follow. As discussed later, recent Australian experiences indicate that the status quo will not be sufficient to both mount a successful public health response to climate-related extreme events and maintain a strong public health infrastructure

In what ways does the mandatory nature of Victoria's municipal public health planning framework impact on the planning process and outcomes?

BACKGROUND: Systems for planning are a critical component of the infrastructure for public health. Both in Australia and internationally there is growing interest in how planning processes might best be strengthened to improve health outcomes for communities. In Australia the delivery of public health varies across states, and mandated municipal public health planning is being introduced or considered in a number of jurisdictions. In 1988 the Victorian State government enacted legislation that made it mandatory for each local government to produce a Municipal Public Health Plan, offering us a 20-year experience to consider. RESULTS: In-depth interviews were undertaken with those involved in public health planning at the local government level, as part of a larger study on local public health infrastructure and capacity. From these interviews four significant themes emerge. Firstly, there is general agreement that the Victorian framework of mandatory public health planning has led to improvements in systems for planning. However, there is some debate about the degree of that improvement. Secondly, there is considerable variation in the way in which councils approach planning and the priority they attach to the process. Thirdly, there is concern that the focus is on producing a plan rather than on implementing the plan. Finally, some tension over priorities is evident. Those responsible for developing Municipal Public Health Plans express frustration over the difficulty of having issues they believe are important addressed through the MPHP process. CONCLUSION: There are criticisms of Victoria's system for public health planning at the local government level. Some of these issues may be specific to the arrangement in Victoria, others are problems encountered in public health planning generally. In Victoria where the delivery structure for public health is diverse, a system of mandatory planning has created a minimum standard. The implementation of the framework was slow and factors in the broader political environment had a significant impact. Work done in recent years to support the process appears to have led to improvements. There are lessons for other states as they embark upon mandated public health plans

Racial Disparity and Socioeconomic Status in Association With Survival in Older Men with Local/Regional Stage Prostate Cancer: Findings From a Large Community-Based Cohort

BACKGROUND Few studies have examined the outcomes for Hispanic men with prostate carcinoma and incorporated socioeconomic factors in association with race/ethnicity in affecting survival, adjusting for factors on cancer stage, grade, comorbidity, and treatment. METHODS We studied a population-based cohort of 61,228 men diagnosed with local or regional stage prostate carcinoma at age 65 years or older between 1992 and 1999 in the 11 SEER (Surveillance, Epidemiology, and End Results) areas, identified from the SEER-Medicare linked data with up to 11 years of followup. RESULTS Low socioeconomic status was significantly associated with decreasing survival in all men with prostate carcinoma. Those living in the community with the lowest quartile of socioeconomic status were 31% more likely to die than those living in the highest quartile (hazard ratio [HR] of all-cause mortality: 1.31; 95% confidence interval [CI]: 1.25–1.36) after adjustment for patient age, comorbidity, Gleason score, and treatment. The HR remained almost unchanged after controlling for race/ethnicity (HR: 1.32; 95% CI: 1.26–1.38). Compared with Caucasians, the risk of mortality in African American men was marginally significantly higher (HR: 1.06; 95% CI: 1.01–1.11) after controlling for education, and no longer significant after adjusting for poverty, income, or composite socioeconomic variable; the HR was lower for Hispanic men (HR: 0.80; 95% CI: 0.72–0.89) after adjustment for education and other socioeconomic variables. CONCLUSION Racial disparity in survival among men with local or regional prostate carcinoma was largely explained by socioeconomic status and other factors. Lower socioeconomic status appeared to be one of the major barriers to achieving comparable outcomes for men with prostate carcinoma

Randomized pilot study to disseminate caries-control services in dentist offices

BACKGROUND: To determine whether education and financial incentives increased dentists' delivery of fluoride varnish and sealants to at risk children covered by capitation dental insurance in Washington state (U.S.). METHODS: In 1999, 53 dental offices in Washington Dental Service's capitation dental plan were invited to participate in the study, and consenting offices were randomized to intervention (n = 9) and control (n = 10) groups. Offices recruited 689 capitation children aged 6–14 and at risk for caries, who were followed for 2 years. Intervention offices received provider education and fee-for-service reimbursement for delivering fluoride varnish and sealants. Insurance records were used to calculate office service rates for fluoride, sealants, and restorations. Parents completed mail surveys after follow-up to measure their children's dental utilization, dental satisfaction, dental fear and oral health status. Regression models estimated differences in service rates between intervention and control offices, and compared survey measures between groups. RESULTS: Nineteen offices (34%) consented to participate in the study. Fluoride and sealant rates were greater in the intervention offices than the control offices, but the differences were not statistically significant. Restoration rates were lower in the intervention offices than the control offices. Parents in the intervention group reported their children had less dental fear than control group parents. CONCLUSION: Due to low dentist participation the study lacked power to detect an intervention effect on dentists' delivery of caries-control services. The intervention may have reduced children's dental fear

Mammography stages of change in middle-aged women with schizophrenia: An exploratory analysis

BACKGROUND: Health care providers and educators who seek to create health promotion programs and individualized comprehensive care plans for women with schizophrenia are hindered by the lack of data to guide their efforts. PURPOSE: This study tested the hypothesis that women with schizophrenia adhere to mammography screening guidelines at the same rate as other same-age women. The study also investigated the validity of the Health Belief (HB) and Stages of Change (SOC) models for breast cancer screening among women with schizophrenia. METHODS: Socio-demographic and clinical variables, as well as knowledge, attitudes, and barriers were assessed as a function of stage of change related to breast cancer screening in 46 women with schizophrenia. RESULTS: Women with schizophrenia were statistically less likely to be adherent to the screening recommendations than those without schizophrenia. Some support was found for the validity of the HB and SOC models for breast cancer screening in women with schizophrenia. Women in the Precontemplation stage had significantly higher negative attitude scores compared to Contemplation and Action/Maintenance stages (59.7, 45.7, and 43.2, respectively), and there was a trend for more barriers in the Precontemplation group (4.6, 2.6, 2.7 respectively). CONCLUSION: Given the small sample size, further research on the rates of breast cancer screening in women with schizophrenia is warranted. Nonetheless, these data suggest that providers who care for women with schizophrenia may need to make take additional measures to ensure that this population receives appropriate screening so as to not put them at greater risk for a late-stage diagnosis of breast cancer. Furthermore, these pilot data suggest that HB and SOC theory-based interventions may be valid for increasing mammography rates in women with schizophrenia

Design and methods for evaluating an early childhood obesity prevention program in the childcare center setting

BACKGROUND: Many unhealthy dietary and physical activity habits that foster the development of obesity are established by the age of five. Presently, approximately 70 percent of children in the United States are currently enrolled in early childcare facilities, making this an ideal setting to implement and evaluate childhood obesity prevention efforts. We describe here the methods for conducting an obesity prevention randomized trial in the child care setting. METHODS/DESIGN: A randomized, controlled obesity prevention trial is currently being conducted over a three year period (2010-present). The sample consists of 28 low-income, ethnically diverse child care centers with 1105 children (sample is 60% Hispanic, 15% Haitian, 12% Black, 2% non-Hispanic White and 71% of caregivers were born outside of the US). The purpose is to test the efficacy of a parent and teacher role-modeling intervention on children’s nutrition and physical activity behaviors. . The Healthy Caregivers-Healthy Children (HC2) intervention arm schools received a combination of (1) implementing a daily curricula for teachers/parents (the nutritional gatekeepers); (2) implementing a daily curricula for children; (3) technical assistance with meal and snack menu modifications such as including more fresh and less canned produce; and (4) creation of a center policy for dietary requirements for meals and snacks, physical activity and screen time. Control arm schools received an attention control safety curriculum. Major outcome measures include pre-post changes in child body mass index percentile and z score, fruit and vegetable and other nutritious food intake, amount of physical activity, and parental nutrition and physical activity knowledge, attitudes, and beliefs, defined by intentions and behaviors. All measures were administered at the beginning and end of the school year for year one and year two of the study for a total of 4 longitudinal time points for assessment. DISCUSSION: Although few attempts have been made to prevent obesity during the first years of life, this period may represent the best opportunity for obesity prevention. Findings from this investigation will inform both the fields of childhood obesity prevention and early childhood research about the effects of an obesity prevention program housed in the childcare setting. TRIAL REGISTRATION: Trial registration number: NCT0172203

Prevention of non-communicable disease in a population in nutrition transition: Tehran Lipid and Glucose Study phase II

<p>Abstract</p> <p>Background</p> <p>The Tehran Lipid and Glucose Study (TLGS) is a long term integrated community-based program for prevention of non-communicable disorders (NCD) by development of a healthy lifestyle and reduction of NCD risk factors. The study begun in 1999, is ongoing, to be continued for at least 20 years. A primary survey was done to collect baseline data in 15005 individuals, over 3 years of age, selected from cohorts of three medical heath centers. A questionnaire for past medical history and data was completed during interviews; blood pressure, pulse rate, and anthropometrical measurements and a limited physical examination were performed and lipid profiles, fasting blood sugar and 2-hours-postload-glucose challenge were measured. A DNA bank was also collected. For those subjects aged over 30 years, Rose questionnaire was completed and an electrocardiogram was taken. Data collected were directly stored in computers as database software- computer assisted system. The aim of this study is to evaluate the feasibility and effectiveness of lifestyle modification in preventing or postponing the development of NCD risk factors and outcomes in the TLGS population.</p> <p>Design and methods</p> <p>In phase II of the TLGS, lifestyle interventions were implemented in 5630 people and 9375 individuals served as controls. Primary, secondary and tertiary interventions were designed based on specific target groups including schoolchildren, housewives, and high-risk persons. Officials of various sectors such as health, education, municipality, police, media, traders and community leaders were actively engaged as decision makers and collaborators. Interventional strategies were based on lifestyle modifications in diet, smoking and physical activity through face-to-face education, leaflets & brochures, school program alterations, training volunteers as health team and treating patients with NCD risk factors. Collection of demographic, clinical and laboratory data will be repeated every 3 years to assess the effects of different interventions in the intervention group as compared to control group.</p> <p>Conclusion</p> <p>This controlled community intervention will test the possibility of preventing or delaying the onset of non-communicable risk factors and disorders in a population in nutrition transition.</p> <p>Trial registration</p> <p>ISRCTN52588395</p
