  • Background
  • Data Sources & Collection Method
  • Univariate Analysis (1)
  • Multivariate Analysis (2)
  • Qualitative Analysis (3)
  • Conclusion
            • Data shows kids who eat more fruits and vegetables and engage in physical activity are less likely to experience mental health issues. Socioeconomic status, however, plays a larger role.
background
Background

Adolescence is key!

Causes of Mental Illness

Research on Adults..but what about kids?

Why is this important?

Clayton SL, Brindis, CD, Hamor JA, Raiden-Wright H, Fong, C. (2000). Investing in Adolescent

Health: A Social Imperative for California’s Future. San Francisco, CA: University of California, San Francisco. National Adolescent Health Information Center.

data collection
Data Collection

RDD telephone survey of land / cell phone lines in CA

41 single county strata & 3 multi-county strata of 17 counties

1 Adult & 1 Adolescent

N = 3,638 adolescents

variables operational measures
Variables & Operational Measures

Unit of Analysis: Adolescents in the State of CA

Dependent Variable: Mental Health Status as measured by “feelings of depression within the last 30 days”

Independent Variables: Eating & Exercise habits

univariate analysis 1
Univariate Analysis (1)

Is mental health normally distributed? (No!)

1 = All of the Time

2 = Most of the Time

3 = Some of the Time

4 = Not very much of the Time

5 = Not at All

.5% = All of the Time

77.3% = Not at All

Skewness = -2.303

univariate analysis
Univariate Analysis

Are good eating habits normally distributed? (No!)

1 = Yes

2 = No

21.8% = Yes

78.2= No

Skewness = -.1.369

univariate 1 analysis
Univariate (1) Analysis

Are good exercise habits normally distributed? (Somewhat)

multivariate analysis 2

Regression Analysis reveals that more fruits/veggies & more exercise =less depression

What effects how much exercise/fruits/veggies a kid gets?

Maybe SES…

Multivariate Analysis (2)

R squared = .015

There is a correlation, but its weak …..

multivariate analysis 21

Crosstab of SES & depression reveals a correlation- 81% of kids in top SES class not at all depressed compared with 61% of kids in the bottom SES (4% vs. 11% for “sometimes depressed)

  • Regression of fruits/vegs & activity has less predictive value than SES alone
Multivariate Analysis (2)

R squared for fruits/vegs & exercise & depression = .015

R squared for SES & depression = .020

R squared for SES & exercise = .023

*knowing exercise only increased predictive value by 3% (but forecast accuracy does increase by 50% more than knowing just fruits/vegs)...SES is most significant

qualitative data 3
Qualitative Data (3)

7 question, open-ended survey

 Example Questions --

  • How do life style choices like eating and exercise habits influence the mental health of adolescents?
  • Drawing on experiences from your patients, have you noticed any correlation between lack of exercise and/or unhealthful eating habits and poor mental health?
qualitative analysis 3
Qualitative Analysis (3)

Question 1: How do life style choices like eating and exercise habits influence the mental health of teens?

qualitative analysis highlights
Qualitative Analysis Highlights

42% Of total responses indicated diet & exercise make adolescents feel better (endorphins) when dealing with depression

37% said higher levels of diet/exercise led to improved self-esteem in kids

conclusion
Conclusion

There is a link…but its weak

Qualitative Data Confirms

SES is more predictive

Why?

What can I take away from this?
