T ra n sp a ren c y # 2 BODY IMAGE: The picture you have in your mind of the way you look from the top of your head to the tip of your toes. WHAT? What is body image? • A multidimensional construct • Consists of: *weight and shape concern *body dissatisfaction Weight and Shape Concern • refers to a preoccupation with or overconcern about issues related to weight, shape, and size along with a self valuation based largely in terms of weight and shape (Allen et al., 2008). •Affective and cognitive/investment components of body image Body Dissatisfaction • subjective negative evaluation of one’s body or body parts (Allen et al., 2008). •Spans the evaluative and affective components SHARED RISK FACTOR • Weight and shape concern is a shared risk factor for both eating disorders and obesity. – the best predictor of binge eating in a prospective study of children and adolescents (Allen et al., 2008) – Linked to disordered eating (McCabe, Ricciardelli & Holt, 2005) and general psychological distress(Perrin et al,., 2010) Feeling Fat versus Being Fat? •The role of weight and shape concern is hypothesized as a factor that could account for the individual differences in the psychological outcomes evidenced in overweight/obese children and youth (Allen et al., 2006). SHARED RISK FACTOR • Body image dissatisfaction is a shared risk factor for both eating disorders and obesity. – Robust risk factor for eating disorders (Stice, 2002) – Implicated in binge eating (Johnson & Wardle, 2005) and decreased physical activity (Neumark-Sztainer et al., 2006) WHY? Why body image? • Body image is relevant to a broad spectrum of weight-related issues (NeumarkSztainer et al., 2007). • It is a popular phenomenon (Choate, 2005). Normative Discontent (Rodin et al., 1985) • Excessive thinness is so pervasively depicted that being discontent with our bodies is now understood as the norm WHY? Why body image? • Body image is relevant to a broad spectrum of weight-related issues. • It is a popular phenomenon. • It’s a numbers game (Neumark-Sztainer et al., 2002,2006,2007; McVey et al., 2004). With A Proper Diet, Moderate but Consistent Exercise, & A Healthy Mindset, I Should Be Able To Fit In Fine WHY? Why body image? • Body image is relevant to a broad spectrum of weight-related issues. • It is a popular phenomenon. • It’s a numbers game. • BECAUSE BODY SATISFACTION PREDICTS LESS WEIGHT GAIN OVER TIME! (NeumarkSztainer et al., 2006a&b, 2007) WHO? Who should we target with healthy body image messaging? • Girls AND boys (McVey et al. 2004) THE MALE IDEAL… has become more muscular to the point of outlandish measurements. Over time, GI Joe has remained popular but his biceps have “grown.” 1964 – 12.2” (31.0 cm) 1974 – 15.2” (38.6 cm) 1994 – 16.4” (41.7 cm) 1998 – 26.8” (68.1 cm) • Her proportions would be totally unrealistic! 38” (96.5cm) 7’2” 219.5cm 18” (45.7cm) 28” (71.1cm) SIZE 3 feet • She would topple over at the waist because it couldn’t support her upper body. • She actually wouldn’t be able to stand on her tiny tiptoed SIZE 3 feet. WHERE? Where is body image important? WHEN? When is body image an important construct? WHEN? • Children as young as 7 show signs of body dissatisfaction (Riccardelli & McCabe, 2001). • 20% of 9-year-old girls and 17% of 9-year-old boys were trying to lose weight (Field et al., 1999). • 26% of Canadian children (ages 2-17) are overweight (Lau et al., 2007). • 25% of teen girls are engaging in at least one symptom of an eating disorder (Jones et al., 2001). • 30% of girls and 24.5% of boys (ages 10-14) were dieting to lose weight in a recent Canadian sample DESPITE BEING IN THE HEALTHY WEIGHT RANGE (McVey et al., 2005). HOW? How do we foster healthy body image? In Schools… In the Workplace… At Home… • Body image is everybody’s business • Ecological, environmental and holistic approaches Conclusions: Key Messages • Body satisfaction predicts less weight gain over time • “Feeling fat may be more important than being fat” in terms of the psychological wellbeing of adolescents. • Stop the focus on weight (at least in terms of prevention) Future Directions • Combining eating disorders & obesity prevention initiatives • Impetus for change beyond the individual • Body image, broadly defined, as a common factor?
