Western Diet Linked to ADHD A new study from Perth's Telethon Institute for Child Health Research shows an association between ADHD and a 'Western-style' diet in adolescents.
Leader of Nutrition studies at the Institute, Associate Professor Wendy Oddy, said the study examined the dietary patterns of 1800 adolescents from the long-term Raine Study and classified diets into 'Healthy' or 'Western' patterns. “We found a diet high in the Western pattern of foods was associated with more than double the risk of having an ADHD diagnosis compared with a diet low in the Western pattern, after adjusting for numerous other social and family influences,” Dr Oddy said. “We looked at the dietary patterns amongst the adolescents and compared the diet information against whether or not the adolescent had received a diagnosis of ADHD by the age of 14 years. In our study, 115 adolescents had been diagnosed with ADHD, 91 boys and 24 girls.” A “healthy” pattern is a diet high in fresh fruit and vegetables, whole grains and fish. It tends to be higher in omega-3 fatty acids, folate and fibre. A “Western” pattern is a diet with a trend towards takeaway foods, confectionary, processed, fried and refined foods. These diets tend to be higher in total fat, saturated fat, refined sugar and sodium. “When we looked at specific foods, having an ADHD diagnosis was associated with a diet high in takeaway foods, processed meats, red meat, high fat dairy products and confectionary,” Dr Oddy said. “We suggest that a Western dietary pattern may indicate the adolescent has a less optimal fatty acid profile, whereas a diet higher in omega-3 fatty acids is thought to hold benefits for mental health and optimal brain function. “It also may be that the Western dietary pattern doesn't provide enough essential micronutrients that are needed for brain function, particularly attention and concentration, or that a Western diet might contain more colours, flavours and additives that have been linked to an increase in ADHD symptoms. It may also be that impulsivity, which is a characteristic of ADHD, leads to poor dietary choices such as quick snacks when hungry.” Dr Oddy said that whilst this study suggests that diet may be implicated in ADHD, more research is needed to determine the nature of the relationship. “This is a cross-sectional study so we cannot be sure whether a poor diet leads to ADHD or whether ADHD leads to poor dietary choices and cravings,” Dr Oddy said. ADHD is the most commonly diagnosed childhood mental health disorder and has a prevalence of approximately 5%. ADHD is known to be more common in boys. The Raine Study is jointly conducted by the Telethon Institute for Child Health Research and The School of Women's and Infant's Health at the University of Western Australia.

30 Million to Benefit from Health Reform Law
Premium subsidies, bans on higher premiums and coverage denials based on gender, and required maternity and newborn care coverage among most significant in reducing women's exposure to health costs.
Thirty million women will benefit from the new health reform law over the next decade, either through new or strengthened insurance coverage, according to a new report from The Commonwealth Fund.
In the first analysis of its kind, the authors report that the law will stabilize and reverse the growing exposure to health costs that women now experience by subsidizing health insurance for up to 15 million currently uninsured women, and strengthening existing coverage for 14.5 million women who are considered underinsured - those who have health coverage that does not adequately protect them from high medical expenses.
Provisions important to women will expand eligibility for Medicaid; provide subsidies to purchase insurance; limit out-of-pocket spending; prevent insurers from charging higher premiums or denying coverage based on health status or gender; and require new plans to cover maternity and newborn care. These provisions will also help uninsured women who earn too much to qualify for Medicaid or premium subsidies gain comprehensive coverage.
Although women are just as likely to be uninsured as men, their health care needs leave them more vulnerable to high health care costs and problems related to loss of health insurance. Because insurance carriers consider women, particularly those of reproductive age, higher risk than men, women report greater difficulties gaining coverage in the individual insurance market and are charged much higher premiums for the same benefits than men of the same age. Further, most individual policies do not cover pregnancy.
Another important provision that will help an estimated 100,000 uninsured women gain coverage is the Pre-Existing Condition Insurance Plan (PCIP) to provide temporary coverage to adults with pre-existing conditions who are uninsured during 2010 to 2013. Seventeen states and the District of Columbia began enrollment in PCIPs in July, and 12 will begin to enroll adults in August; in the 21 states without a PCIP the federal government began operation of a PCIP July 1st.
"Historically, women have been more vulnerable to high health care costs and have had greater difficulty paying medical bills because of their lower incomes," said Commonwealth Fund President Karen Davis. "This report provides good news to all women, who will be more likely to get the care they need, with reduced risk of incurring the unaffordable medical bills that have affected so many Americans."
Realizing Health Reform's Potential: Women and the Affordable Care Act of 2010 is the first in a series of Fund reports that will focus on how health reform is expected to impact various populations. It describes when provisions of the new law affecting women take effect, and how many women will be affected by specific provisions. Beginning in 2014, Medicaid coverage expansions and subsidized coverage through state health insurance exchanges could assist 15 million working-age women who currently lack insurance. The majority of these gains come from Medicaid coverage expansions that may affect up to 8 million currently insured women who earn up to $14,000 or are in families with incomes up to $29,000.
Women living in states with higher than average uninsurance rates stand to gain the most from the new law: New Mexico and Texas (29% uninsured in 2008); Florida and Louisiana (24% uninsured); and Alaska, Arizona, Arkansas, California, Georgia, Mississippi, West Virginia, Idaho, Kentucky, Nevada and Oklahoma (at least 20% uninsured).
Although women will have to wait until 2014 to begin to reap the greatest benefits from expanded and improved insurance coverage, several early provisions beginning in 2010 will also provide important support, the study shows. These include:
Strengthened and expanded insurance coverage for young adults, through policies that allow adult children up to age 26 to come on, or stay on, their parents' plans, and bans on pre-existing condition exclusions;
Bans on lifetime benefit limits and phase-out of annual limits;
Bans on rescissions of insurance policies;
Coverage of recommended preventive services without cost-sharing including mammograms;
Eligibility for a new plan that covers uninsured people with pre-existing conditions that currently make it difficult for them to gain coverage; and
Rebates to women enrolled in Medicare who reach the "doughnut hole" in their prescription drug plans; women, along with people with diabetes and Alzheimer's or other forms of dementia are most likely to reach this gap in coverage.
Nearly two in five women - an estimated 7.3 million - between the ages of 19 and 64 who tried to buy individual insurance plans over a three-year period were turned down, charged a higher price or had a pre-existing condition excluded from their plan. Beginning in 2014, all insurers must accept everyone who applies for coverage and cannot charge higher premiums based on health status or gender.
In addition, all health plans sold through new state insurance exchanges in both the individual and small group markets will have to cover maternity and newborn care as part of the federally determined benefit packages described below.
"Women who have an individual insurance market policy that charges them higher premiums than men, who have been unable to secure coverage for the cost of a pregnancy, or who have a preexisting health condition excluded from their benefits will ultimately find themselves on a level playing field with men, with a full range of comprehensive benefits, including maternity coverage," said lead study author Sara Collins, a vice president at the Commonwealth Fund.
Uninsured women who earn too much to qualify for Medicaid will be able to purchase policies through staterun exchanges that will offer federally determined essential benefit plans with four levels of cost-sharing with an annual cap on out-of-pocket costs of $5,950 for individuals and $11,900 for families, beginning in 2014. In addition, women with incomes under 400 percent of poverty, or $88,000 for a family of four, will be eligible for subsidies to offset their premiums and out-of-pocket costs. Up to 7 million currently uninsured women may gain subsidized coverage through the exchanges.
"Today many health plans don't provide a comprehensive set of affordable benefits, forcing women to choose between paying out-of-pocket for necessary service or delaying or skipping care. Better information and benefit plans that are easier to understand, along with subsidies to offset their costs, will make a significant difference for American families," said Collins.
Women who own businesses with fewer than 50 or 100 employees, depending on the state, will also be able to purchase a health plan through the exchanges.
