  • Background and context related to excess weight

  • What do we know works?

    • Systematic review of weight loss strategies

  • Promising approaches to address excess weight for employed populations

Excess Weight

  • Overweight prevalence in the U.S. exceeds 65% of the population

  • Excess weight is associated with a variety of diseases, disorders, disability, function, quality of life, musculoskeletal pain, diminished social functioning, and premature death

Optimal, best possible performance, fully present

Fully absent, no work or duties performed

Worst possible performance, fully present

Excess Weight

  • Excess weight impacts on both direct costs and indirect costs for employers

Health is more than the absence of disease…

  • Despite proclamations to the value of health, morbidity and mortality are what counts and gets counted (i.e., measured)

  • Evaluations are primarily based on reductions in mortality and morbidity, and their known behavioral risk factors, such as PA and diet

  • Do individuals characterized as being in “complete health” incur less health care costs and are they more productive than those characterized as being in “incomplete health” or “complete ill health”?

Does Health as a Complete State add Benefit to the Bottom Line?

Productivity and Health RisksObesity and Work Limitations

  • Obesity impact on work limitations

  • NHANES III and NHANES 1999-2000 data

  • Obese workers, regardless of gender, are more likely than normal weight workers to report being limited in the amount or type of work they can do because of physical, mental or emotional problems (6.9% vs. 3.0%, respectively)

Impact of obesity on work limitations is akin to 20 years of aging

What do we know works?

  • Basing decisions on evidence is a good idea

  • By and large, the best evidence for many decisions comes from a systematic review of all the evidence

  • Systematic reviews currently provide the best, least biased, and rational way to organize, cull, evaluate, and integrate the available research evidence

HealthPartners Systematic Review on Obesity

  • Study question:

    • “What lifestyle strategies and/or treatment components contribute to successful weight management defined as 5% to 7% of starting (baseline) body weight, 5% loss maintained for 1 year or longer?”

  • Studies published after January 1997

    • Randomized controlled trials 12 months in duration

    • Observational studies 5 years in duration

    • Meta-analysis of studies meeting study criteria

  • Results presented by intervention type

    • Advice-only; diet-only; diet plus PA; exercise-only; meal replacements; VLCD; anti-obesity medications

Literature Review

  • Diet advice only

    • 16 studies with diet advice alone as 1 arm: 3,786; 3,418 completers

  • Exercise alone

    • 4 studies; 6 studies with exercise alone as 1 arm: 325; 260 completers

  • Diet the primary therapy

    • 8 studies; 39 studies with diet alone as 1 arm: 7,798; 4,979 completers

  • Diet plus exercise

    • 13 studies; n=2,183; 1,950 completers

  • Meal replacements

    • 8 studies; n=470; 376 completers

  • Anti-obesity medications

    • 21studies; n=6,634; 4.241 completers

  • Very-low calorie diets

    • 11studies; n=925; 551 completers

      Total: 80 studies; N=24,698; 16,823 completers (68%)

Task Force on Community Preventive Services

  • Obesity-related systematic review for worksite setting

    • Multi-component interventions aimed at diet, physical activity, and cognitive change


    • Single component interventions aimed at diet, physical activity, or cognitive change alone

Promising Approaches

  • Program strategy and design elements

    • Clear goals and objectives

    • Strong leadership

    • Socio-ecological approach recognizing both individual-level and organizational-level program characteristics

    • Program intensity and cost

    • Communications and incentives

    • Inter-relatedness of all elements

Program Elements to Consider

  • Program intent

  • Intervention target level

  • Intervention design features

  • Program intensity and cost

  • Target population

  • Program approaches (tactics; options)

Program Components Related to Successful Outcomes

  • Behavioral weight loss strategies:

    • Calorie reduction

    • Fat reduction

    • Increased fruit/vegetable intake

    • Increased exercise/physical activity

    • Elimination of sweets

    • Consumption of less food

  • Any use of strategies (singly or in combination) is associated with weight loss

  • Use of these strategies is related to better weight loss in a dose-response fashion

Source: Linde, et al Int J Behav Nutr Phys Act 2006, 3(3) [access online].

Program Components Related to Successful Outcomes

  • Successful weight loss maintenance

    • Dietary composition – moderately low fat diet consumption and total caloric intake monitoring

    • Breakfast – 7 days per week

    • Self-monitoring – daily or weekly monitoring of body weight

    • Physical activity – regular PA; 1 hour of moderate intensity PA daily (or ~28 miles of walking per week)
