K. Park et Jr. Ureda, Specific motivations of milk consumption among pregnant women enrolled in or eligible for WIC, J NUTR EDUC, 31(2), 1999, pp. 76-85
To identify motivational determinants of milk consumption, a major source o
f prenatal calcium intake, 180 pregnant women drawn from two prenatal clini
cs in South Carolina were surveyed. Most of them were enrolled in or eligib
le for the Special Supplemental Nutrition Program for Women, Infants and Ch
ildren (WIC Program). The Theory of Planned Behavior was used to design an
instrument assessing attitudinal, subjective normative, and perceived contr
ol beliefs toward consuming milk. Motivational beliefs explaining milk cons
umption were first explored using univariate regression (p < .05), and a se
t of salient beliefs was identified using multiple regression with backward
elimination (p < .1). Multiple regression models based upon these factors
explained more than 49% of the variability in motivation for milk consumpti
on (p = .0001). Practical reasons for consuming milk including "taste" and
"quench thirst" and perceived health consequences were among attitudinal be
liefs included in the models. "Husband/boyfriend," "doctor," and "nurse/WIC
staff/nutritionist" were identified as social influences, and perceived co
nfidence in "keeping milk fresh," "keeping milk at home for me," "buying/ge
tting milk whenever I wanted to," and "being able to drink two cups a day"
were among perceived control beliefs contributing to the models. These beli
efs provide a basis for targeted prenatal educational interventions, which
should include strategies addressing all three factors described in the Pla
nned Behavior model.
