´╗┐The Correlational Relationship Between Binge Eating and Depression: A Meta-Analytic Review Susan Himes, Liuqin Yang, & Tovah Yanover University of South Florida November 25, 2005

Slide 2

Why is Binge Eating Important? Voraciously consuming food unsettling influence is thought to be a huge clinical issue since it is connected with despondency, nervousness, and other psychopathology (Womble, 2001). Notwithstanding the negative mental relates of gorging, voraciously consuming food is a hazard figure for corpulence and weight pick up (McGuire et al., 1999; Stice et al., 1999; Stice, Presnell, & Spangler, 2002).

Slide 3

What is Binge Eating and Which Populations are Prone to Binges? The American Psychiatric Association (1994) characterizes pigging out as the utilization of a lot of nourishment inside a discrete timeframe, joined by saw loss of control. Voraciously consuming food conduct has been seen in both clinical eating confused gatherings and nonclinical tests (Bruce & Agras, 1992; Fairburn, Hay, & Welch, 1993.); in any case, pigging out conduct is regularly found among fat and bulimic populaces.

Slide 4

What is the Relationship Between Binge Eating and Depression? Past studies have found that voraciously consuming food issue is connected with a more prominent lifetime chance for significant sorrow (Marcus et al., 1990; Yanovski et al., 1993). Orgy eaters show more elevated amounts of current misery (Telch & Agras, 1996). Stice (2002) found that depressive side effects anticipated an expanded hazard for voraciously consuming food onset in juvenile young ladies.

Slide 5

What is the Relationship Between Binge Eating and Negative Affect? Despite the fact that not each fling scene happens inside the setting of discouragement, negative effect or negative temperament state much of the time predicts the start of a fling (Stice & Agras, 1998; Arnow, Kenardy, and Agras, 1995). Stice (1998) found that negative influence anticipated voraciously consuming food in immature young ladies, despite the fact that this impact was not saw in grown-up ladies (Vogeltanz-Holm et al., 2000). There is additionally exploratory proof that negative influence acceptances result in hoisted caloric admission among grown-up health food nuts, and that negative mind-set states have a tendency to go before voraciously consuming food scenes among people with bulimia nervosa and gorging jumble (BED; Cools, Schotte, & McNally, 1992; Davis, Freeman, Garner, 1988; Greeno, Winge, & Shiffman, 2000).

Slide 6

Affect Regulation Model (Stice, 2005) The influence direction display proposes that people in a pessimistic mind-set state eat with an end goal to give solace or diversion from contrary feelings. People with aggravations in serotonin direction (which describe sadness) may expend unreasonable measures of starch rich sustenances with an end goal to control their serotonin levels (Wurtman et al., 1985). Dietary or pharmacological serotonin organization prompts to standardized eating and diminished dejection (Ciarella, Ciarella, Graziani, & Mirante, 1991; Lieberman, Wutmasn, & Chew, 1986). Confirm for the Affect Regulation Model: Depression has anticipated future increments in weight in grown-ups (Hoppa & Hallstrom, 1981; McGuire et al., 1999) and future increments in body mass and onset of stoutness in teenagers (Goodman & Whitaker, 2002; Pine, Goldstein, Wolk, & Weissman, 2001). In a vast specimen of youthful young ladies, Stice (2005) found for each extra depressive manifestation reported, there was more than a fourfold increment in hazard for heftiness onset.

Slide 7

Strength of the Relationship Between Binge Eating and Depression Only a couple concentrates on tended to the quality of the relationship amongst gorging and wretchedness. In 1993, Berkowitz, Stunkard, and Stallings found that wretchedness was identified with the seriousness of pigging out in treatment looking for corpulent female young people. Greenberg and Harvey (1996) found that seriousness of voraciously consuming food was fundamentally associated with the conjunction of large amounts of despondency and dietary limitation. Isnard (2003) found a solid critical positive relationship between voraciously consuming food seriousness and level of melancholy among corpulent teenagers looking for treatment. Streigel-Moore et al. (1998) found that, in a fat populace, subjects with subthreshold BED and overeaters tended to demonstrate larger amounts of depressive qualities than the non-pigging out control assemble, showing a continuum of expanding wretchedness hazard with expanding gorging.

Slide 8

Which Samples Have a Stronger Relationship Between Binging and Depression? Clinical specimens measuring the relationship amongst sadness and gorging symptomatic status have reliably found that hefty bingers encounter higher rates of gloom than large non-bingers (Stice & Telch, 1998, Streigel-Moore et al, 1998). Among eating scattered specimens, larger amounts of misery have been accounted for in bulimia tests than in voraciously consuming food issue tests (Crow et al., 1996; Raymond et al., 1995). Interestingly, Peterson et al. (1998) found no distinctions in gloom between BED purgers and BED non-purgers.

Slide 9

Aims of the Current Meta-Analysis Despite the quantity of studies looking at the relationship between mind-set state and voraciously consuming food, the outcomes have not been audited and dissected utilizing meta-logical strategies. The essential point of the current meta-examination is to illuminate the size of the relationship between sorrow/depressive indications and voraciously consuming food conduct. The optional point of this meta-examination is to test for the arbitrator test sort, to distinguish whether the relationship between pigging out and despondency is more grounded in a few populaces (corpulent) than in others (dietary issue tests).

Slide 10

Method Literature seek PsycINFO and PubMed Binge and despondency as catchphrases Studies somewhere around 1994 and 2005 332 studies in PsycINFO and 343 in PubMed Inclusion criteria Binge eating and sadness were operationalized unmistakably and measured. Zero-arrange relationship was accounted for. Just 10 studies were recognized.

Slide 11

Method (Cont') Coding and between rater dependability Seven qualities were coded Categorical factors ( Kappa ): Research setting, test sort, members' sex and p-estimations of impact sizes Continuous factors ( ICC ): Sample size and impact estimate Procedure Measurement blunder , not redressed Barebones examination , Schmidt and Hunter's Moderator investigation , Hedges & Olkin's Q

Slide 14

Results Inter-rater unwavering quality (Table 2) All the Kappa qualities are equivalent to 1 aside from coding of research setting. Both ICCs are more than .99 for persistent study attributes. Relationship between voraciously consuming food and misery (Table 4) Estimated normal of rho is .34.

Slide 17

Results (Cont') Moderator examination Telch et al. (1994) was barred Six from large specimens and 6 from others Q-test demonstrated general heterogeneity ( Q (11) = 28.33, p < .001 ) The trial of our mediator, ns ( Q (1) = 0.72, p=.396 )

Slide 18

Summary Meta-examination uncovered a critical, positive relationship between voraciously consuming food and wretchedness. The information were heterogeneous, yet determination did not essentially direct the relationship.

Slide 19

Moderation Two conceivable reasons that conclusion was not a critical mediator It isn't and future research ought to discover one that is. It is yet we hade excessively few studies (12 impact sizes) to see it.

Slide 20

Implications Findings predictable with influence control show But the information are cross-sectional Of intrigue is the complementary relationship between these builds

Slide 21

Limitations Small k Inclusion of distributed studies

Slide 22

Future Research More concentrates so we can reconsider conclusion as an arbitrator More studies to take a gander at other potential mediators Participant age Participant sexual orientation
