The Fun Families Study: intervention to reduce children's TV viewing.
Media consumption may contribute to  childhood obesity . This study developed and evaluated a theory-based , parent-focused intervention to reduce television and other media consumption to prevent and reduce childhood obesity .  Families ( n = 202 ) with children ages 6 - 9 were recruited from a large , urban multiethnic population into a r and omized controlled trial ( 101 families into the intervention group and 101 into the  control group ) , and were followed for 6 months . The intervention consisted of a 2-hour workshop and six bimonthly newsletters . Behavioral objectives included : ( i ) reduce TV watching ; ( ii ) turn off TV when nobody is watching ; ( iii ) no TV with meals ;  ( iv ) no TV in the child 's bedroom ; and ( v ) engage in fun non-media related activities .  Parents were 89 % female , 44 % white , 28 % African American , 17 % Latino , and 11 % Asian , mean age 40 years ( s.d . = 7.5 ) ; 72 % were married . Children were 49 % female , mean age 8 years ( s.d . = 0.95 ) . Sixty-five percent of households had three or more TVs and video game players ; 37 % had at least one h and held video game , and 53 % had three or more computers . Average children 's weekday media exposure was 6.1 hours . At 6 months follow-up , the intervention group was less likely to report the TV being on when nobody was watching ( adjusted odds ratio ( AOR ) = 0.23 , P < 0.05 ) , less likely to report eating snacks while watching TV ( AOR = 0.47 , P < 0.05 ) , and less likely to have a TV in the child 's bedroom ( AOR = 0.23 , P < 0.01 ) . There was a trend toward reducing actual media consumption but these outcomes did not reach statistical significance . Effective strategies to reduce children 's TV viewing were identified
