Healthy lifestyle cuts Alzheimer’s risk

A healthy lifestyle in middle age is key to staving off Alzheimer’s disease and dementia, says a new study.According to two senior doctors, keeping obesity, blood pressure and cholesterol under control as you age can cut the risk of developing Alzheimer’s and dementia by 20 per cent, reports “The Daily Express.”The study, by Tom Russ and John Starr, has appeared in the journal BMJ Clinical Evidence.

Their article stated: “Consistent with the finding that there are pathological changes well in advance of the appearance of symptoms of dementia, evidence is mounting that preventative efforts must be introduced sufficiently early in life to have an effect.
“Blood pressure, cholesterol and obesity need to be adequately controlled in midlife for dementia to be prevented. Exercise is to be recommended across all age groups.”
Rebecca Wood, chief executive of the Alzheimer’s Research Trust, said: “Diet and lifestyle almost certainly play a part in every person’s Alzheimer’s risk.

Taxes on soda do little to prevent obesity
Small sales taxes on soft drinks are insufficient to curb soda consumption among children, a new American study has revealed.
The RAND Corporation study points out that these small taxes may reduce consumption in some subgroups such as children at greater risk for obesity, but reducing consumption for all children would require larger taxes. Lead author Roland Sturm, a senior economist at RAND, a nonprofit research organization, said: "If the goal is to noticeably reduce soda consumption among children, then it would have to be a very substantial tax.“A small sales tax on soda does not appear to lead to a noticeable drop in consumption, led alone reduction in obesity.”

Taxes on soft drinks and other sugar-sweetened beverages have been proposed as part of many anti-obesity efforts, with the goal being to discourage consumption of the high-calorie drinks in order to curb excess weight gain.
The study team estimated the potential effect of soft drink taxes on children's consumption and weight by examining differences in existing sales taxes on soft drinks between states.

HIV risk factor for teens: Crack and cocaine use
Teens with a history of crack or cocaine are at an increased risk for HIV than youth who have never used these drugs, claims a new study.

The study has been published in the April issue of the Journal of Child and Adolescent Substance Abuse.Bradley Hasbro Children’s Research Center boffins report that teens in psychiatric care who used crack and/or cocaine at least once were six times more likely to use condoms inconsistently, which was defined as “sometimes,” “never” or “rarely.”
The findings in the study suggest that crack cocaine appears to have more of an influence on risky teen behaviours than other factors, like smoking, alcohol and marijuana use, which are more routinely incorporated into adolescent HIV prevention interventions.
