Factors associated with nutrition label use among female college students applying the theory of planned behavior

BACKGROUND/OBJECTIVESUse of nutrition labels in food selection is recommended for consumers. The aim of this study is to examine factors, mainly beliefs explaining nutrition label use in female college students based on the Theory of Planned Behavior (TPB).SUBJECTS/METHODSThe subjects were female college students from a university in Seoul, Korea. The survey questionnaire was composed of items examining general characteristics, nutrition label use, behavioral beliefs, normative beliefs, corresponding motivation to comply, and control beliefs. The subjects (n = 300) responded to the questionnaire by self-report, and data from 275 students were analyzed using t-test or χ²-test.RESULTSThe results showed that 37.8% of subjects were nutrition label users. Three out of 15 behavioral beliefs differed significantly by nutrition label use. Nutrition label users agreed more strongly on the benefits of using nutrition labels including ''comparing and selecting better foods'' (P < 0.001), ''selecting healthy foods'' (P < 0.05). The negative belief of ''annoying'' was stronger in non-users than in users (P < 0.001). Three out of 7 sources (parents, siblings, best friend) were important in nutrition label use. Twelve out of 15 control beliefs differed significantly by nutrition label use. These included beliefs regarding constraints of using nutrition labels (e.g., time, spending money for healthy foods) and lack of nutrition knowledge (P < 0.001). Perceived confidence in understanding and applying the specifics of nutrition labels in food selection was also significantly related to nutrition label use (P < 0.001).CONCLUSIONSThis study found that the beliefs, especially control beliefs, suggested in the TPB were important in explaining nutrition label use. To promote nutrition label use, nutrition education might focus on increasing perceived control over constraints of using nutrition labels, acquiring skills for checking nutrition labels, as well as the benefits of using nutrition labels and receiving support from significant others for nutrition label use.     

Theory of planned behavior to promote physical activity of adults with physical disabilities: Meta-analytic structural equation modeling

BackgroundAdults with physical disabilities experience lower physical activity (PA) engagement. The theory of planned behavior (TPB) has been one of dominant theories in understanding and promoting PA. There is no previous meta-analysis examining the use of the TPB on PA of adults with physical disabilities.ObjectiveThe purposes of this review were 1) to conduct meta-analysis to examine predictive effects of TPB on PA behavior of adults with physical disabilities and 2) to investigate a possible moderator among components of TPB.MethodsOne-stage meta-analytic structural equation modeling was used to conduct meta-analysis. Type of physical disability was examined as a moderator.ResultsIntention had moderate effect on PA (β = 0.37, p < .001), attitude had a moderate effect on intention (β = 0.30, p < .001), SN had a non-significant effect on intention (β = 0.03, p = .75), and PBC had a moderate effect on intention (β = 0.43, p < .001) and a non-significant direct effect on PA (β = 0.09, p = .18). The studies conducted with only participants with SCI lowered the predictive effect (β = ?0.12, p = .02) of PBC on PA.ConclusionsPredictive effects of component of TPB were slightly different from those of individuals without disabilities. Type of physical disability can be a critical factor determining the impact of perceived control on PA behavior. Attitude and PBC can be targets for promoting PA of adults with physical disabilities.

Season of birth and disordered eating in female college students

OBJECTIVE: Earlier studies have suggested relationships between season of birth and eating disorders. These studies have found that women with anorexia nervosa (AN) and bulimia nervosa (BN) are more likely to be born in the first 6 months rather than in the last 6 months of the year. The current study examines relationships between season of birth and general disordered eating in female college students. METHOD: Subjects included 155 female twin and triplet participants from the Michigan Twin Study. Disordered eating was assessed with subscales from the Minnesota Eating Disorders Inventory (M-EDI) and the Eating Disorders Examination Questionnaire (EDEQ). Both a two-group comparison and a three-group comparison of M-EDI and EDEQ scores were conducted. The two-group comparison comprised subjects born between January and June and subjects born between July and December. The three-group comparison comprised subjects born between January and April, between May and August, and between September and December. RESULTS: No significant differences in M-EDI or EDEQ scores were observed in any of the group comparisons. DISCUSSION: The lack of significant differences across birth periods suggests that season of birth effects may not generalize to general disordered eating characteristics in nonclinical samples.     

Predicting walking as exercise in women with fibromyalgia from the perspective of the theory of planned behavior

ABSTRACT

Based on the theory of planned behavior, this study examined factors related to the intention to adhere to an unsupervised walking program and the intention-behavior gap in relation to walking adherence in women with fibromyalgia. We also accounted for specific variables: fear of movement, pain intensity, distress and disability. TPB constructs, walking behavior and the above-mentioned variables were assessed in 274 women aged 18 to 70 years old (mean 51.8, range 25.5–69.1 years) at baseline and seven weeks later (n = 219) during 2012. Intention to adhere to a walking program showed medium scores at baseline and was associated with attitude and perceived behavioral control (PBC). Self-reported walking adherence at Time 2 was only predicted by perceived behavioral control. The intention-behavior gap was present in 33% of participants. Logistic regression analysis showed PBC associated with being a successful intender. Women with fibromyalgia were motivated to walk; however, they did not act on their intentions, and PBC appeared as the main explanation. Women who perceived high control in comparison to those who perceived low control, increased their likelihood of adhering to a walking program about three-fold. Women with fibromyalgia should increase their perceived control through different strategies     

基于计划行为理论的女性性工作者安全套使用行为影响因素的分析

目的运用计划行为理论来探索低档娱乐场所女性性工作者(FSWs)安全套使用行为的主要影响因素,以期为今后预防艾滋病的行为干预工作提供有针对性的指导。方法按计划行为理论设计问卷,对随州和武汉地区低档场所FSWs进行调查,采用结构方程模型来分析安全套使用行为的影响因素。结果行为态度、主观规范、知觉行为控制对于行为意向的总体影响分别为0.517、0.127和0.086。知觉行为控制、行为意向、行为态度、主观规范对于行为的总体影响分别为0.654、0.183、0.095和0.023。结论行为态度是影响FSWs安全套使用行为意向的最主要因素。知觉行为控制相比行为意向对FSWs人群安全套使用行为的影响更大。     

Factors influencing fast food consumption behaviors of middle-school students in Seoul: an application of theory of planned behaviors

Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high R² around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P < 0.001) and perceived behavioral control (b = 0.19, P < 0.001). Further analysis showed that behavioral intention was significantly related to subjective norm (b = 0.15, P < 0.01) and perceived behavioral control (b = 0.56, P < 0.001). Attitude toward fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control.
