Lessons from the Field: Lessons from Yap - Changing Government and Cultural Practice Through Public Health Policy.

The heavy burden of non-communicable diseases (NCD) in Yap State, Federated States of Micronesia overwhelms the resources of this small population. Traditional cultural practices strongly influence all aspects of life, especially in the remote outer islands. The traditional Chiefs must grant permission to perform any type of health outreach or services for about one-third of the population. One key cultural practice promotes tobacco and alcohol use. The Yap Comprehensive Cancer Control Program, in collaboration with other entities in public health, systematically engaged the traditional Chiefs, resulting in a landmark policy that paved the way for other system and environmental interventions to reduce the risks of developing NCD.

Assessing women's understandings of health in rural Papua New Guinea: implications for health policy and practice.

In Papua New Guinea (PNG), women's health is addressed by applying biomedical solutions which often ignore the complexity of women's histories, cultural contexts and lived experiences. The objective of this study was to examine adult and older women's perceptions of health and well-being to identify priority areas for public service interventions. Rapid ethnographic assessment was conducted in the Wosera district, a rural area of PNG from mid-2005 to early 2006, to examine the health concerns of women. Twenty-seven adult women and 10 older women participated in the study. Health was not limited to one aspect of a woman's life, such as their biology or maternal roles; it was also connected with the social, cultural and spiritual dimensions of women's daily existence. Participants also identified access to money and supportive interpersonal relationships as significant for good health. A disconnect was found to exist between women's understandings of good health and socio-political health policies in PNG, something likely to be repeated in health service delivery to different cultural groups across the Asia Pacific region. Health and development practitioners in PNG must become responsive to the complexity of women's social relationships and to issues relating to the context of women's empowerment in their programmes.

Occupational and environmental medicine in the United States: A proposal to abolish workers' compensation and reestablish the public health model.

The workers' compensation model of occupational and environmental medicine should be converted to a public health model. Occupational and environmental medicine, as a part of the public health infrastructure,could play a much more substantive part in bringing about a national program to deal with occupational and environmental health. The workers' compensation insurance system could be discontinued at any time,but it will be vital to do so when national health insurance is adopted in the United States. Abolishing workers' compensation would remove the perverse incentives that currently undermine the practice of occupational medicine. Medical care for workers should be provided by health care professionals who are not subject to influence by employers or insurers. Eligibility for benefits should not be determined by health and safety professionals. Wage-replacement benefits for workers should be determined by guidelines established by government and industry that prevent manipulation of health and safety professionals by employers and insurers. A nationwide comprehensive system to track work-related injury and illness, superior to the current reliance on records provided by employers and collated by government agencies, should be adopted. When unusually high rates of injuries, illnesses,and fatalities occur, government inspectors ought to respond and regulate the industry accordingly. Occupational health and safety professional strained in public health can and should participate in these activities, but not when they are in the employ of industry or insurers.

Declining rate of folate insufficiency among adults following increased folic acid food fortification in Canada.

OBJECTIVE: Canada introduced a mandatory folic acid food fortification program in November 1998. We investigated whether the rate of folate and vitamin B12 insufficiency among adults has changed since this mandatory fortification program was implemented. METHODS: We conducted a retrospective cross-sectional study using a large Ontario laboratory database. We included all individuals who underwent evaluation of their serum folate, red cell folate and serum vitamin B12 between April 1, 1997 to July 31, 1998 (Period A), August 1, 1998 to January 30, 1999 (Period B) and February 1, 1999 to March 31, 2000 (Period C). RESULTS: A total of 8,884 consecutive samples were analyzed during the period of study. Mean age was 57.4 years (SD 21.1), and 63.2% were female. The prevalence of serum folate insufficiency (below 3.4 nmol/L) fell from 0.52% in Period A to 0.22% in Period C [prevalence ratio (RR) 0.41, 95% confidence interval (CI) 0.18-0.93)]. The prevalence of red cell folate insufficiency (below 215 nmol/L) declined from 1.78% during Period A to 0.41% in Period C (RR 0.23, 95% CI 0.14-0.40). No significant difference was observed between periods in the prevalence of B12 insufficiency below 120 pmol/L (3.93% versus 3.11%, respectively; RR 0.79, 95% CI 0.62-1.01). CONCLUSIONS: There has been a significant decline in the prevalence of folate, but not vitamin B12 insufficiency, following Canadian folic acid food fortification. These changes may have important implications for the prevention and detection of folate and vitamin B12 insufficiency, including identifying the benefits of folic acid food fortification and the need to further consider fortification or supplementation with vitamin B12.

Effectiveness of food fortification in the United States: the case of pellagra.

OBJECTIVES: We evaluated the possible role of niacin fortification of the US food supply and other concurrent influences in eliminating the nutritional deficiency disease pellagra. METHODS: We traced chronological changes in pellagra mortality and morbidity and compared them with the development of federal regulations, state laws, and other national activities pertaining to the fortification of cereal-grain products with niacin and other B vitamins. We also compared these changes with other concurrent changes that would have affected pellagra mortality or morbidity. RESULTS: The results show the difficulty of evaluating the effectiveness of a single public health initiative such as food fortification without controlled experimental trials. Nonetheless, the results provide support for the belief that food fortification played a significant role in the elimination of pellagra in the United States. CONCLUSIONS: Food fortification that is designed to restore amounts of nutrients lost through grain milling was an effective tool in preventing pellagra, a classical nutritional deficiency disease, during the 1930s and 1940s, when food availability and variety were considerably less than are currently found in the United States.
