Is Stress Making You Fat?

Before you reach for the junk food after a rough day at the office, chew on this: A new study found that overweight people gain more when stressed by work.

The American Journal of Epidemiology published a study about the association of stress and weight gain. The research analyzed 1,355 men and women in the U.S., assessing their body mass index (BMI) for multiple domains of psychosocial stress related to work, personal relationships, life constraints, and finances, according to the study abstract.

Both overweight men and women tended to put on the pounds from job-related demands and difficulty paying bills, but women also saw weight gain from family-related matters.

Among men with high baseline BMI, weight gain was associated with increasing level of stress related to job-related demands, lack of skill discretion, lack of decision authority, and difficulty paying bills.

Among women with high baseline body mass index, weight gain was associated with job-related demands, perceived constraints in life, strain in relationships to family, and difficulty paying bills.

The research concluded that addressing psychosocial stress could limit weight gain among overweight and obese men and women.

“This tells us that periods of stress, like we are experiencing right now with the economic decline, can lead to even more weight gain among those who already have a weight problem,” lead author Jason Block, a faculty member at Harvard Medical School, told USA TODAY.  “And weight-loss programs should incorporate stress-reduction techniques as part of their plans to help people lose weight more successfully.”

Fidelity Ups International Equity Exposure in Target-Dates

Fidelity Investments is increasing the international equity exposure and adding Treasury Inflation-Protected Securities to its lifecycle funds.

The investment firm today announced it would bump the asset allocation targets in its Freedom Fund product line for international equities to 30% of total equity exposure from about 20%. The increased international exposure will be funded by a reduction in the allocation to domestic equity funds.

“Freedom Fund shareholders to invest in a portfolio that is more reflective of the risks and opportunities presented in an increasingly global economy,”said  Derek L. Young, chief investment officer of the Global Asset Allocation group for Fidelity Management & Research Company (FMRCo).

In addition, the company said the Fidelity and Fidelity Advisor Freedom Funds will seek further diversification by investing in two new underlying funds with exposure to dedicated commodities and Treasury Inflation-Protected Securities (TIPS): Fidelity Series Commodity Strategy Fund and Fidelity Series Inflation-Protected Bond Index Fund.

The Fidelity Freedom K and Fidelity Freedom Index Funds, offered only to certain retirement plans recordkept by Fidelity, also will feature the higher level of international equity exposure, as well as the dedicated commodities and inflation-protected exposure.

“It’s no secret that inflation erodes a portfolio’s purchasing power, and historically it has been a factor in some major asset classes, such as stocks and bonds, underperforming their historical averages. A notable dimension of commodities is their historical record in providing inflation protection,” said Young. “Adding explicit TIPS exposure can provide a real, inflation-adjusted return as well as additional diversification within the fixed-income asset class.”

Other funds that will see a similar modification in their international equity exposures and the addition of TIPS include the Asset Manager series—including Fidelity, Advisor and VIP versions—and the Fidelity Four-In-One Index Fund.
