Beliefs and attitudes toward “healthier eating” among women attending maternity hospital

Intention of Older Women to Consume 100% Watermelon Juice for Vascular Health: An Application of Theory of Planned Behavior

To strengthen randomized controlled trials (RCT) evaluating the efficacy of 100% watermelon juice on vascular function of older women, theory-driven behavioral analysis as well as comparative sensory analysis of the intervention and placebo were conducted. The Theory of Planned Behavior was adopted to assess psychosocial determinants of intention to consume watermelon juice. Sensory attributes were assessed utilizing hedonic scales. Analysis included Structural Equation Modeling with maximum likelihood. The measurement model provided a good fit (x² = 70.22, df = 38; RMSEA = 0.07, CFI = 0.98; NFI = 0.95). Attitude (γ = 0.36), subjective norm (γ = 0.43), and perceived behavioral control (γ = 0.21,) were significant predictors (p < 0.001) of intention. Participants identified no significant differences in sensorial attributes between beverages, thereby minimizing sensory bias and discrimination. Similar approaches may help other RCT investigating novel foods and bioactive compounds bridge gaps between efficacy and effectiveness.

A Cross Sectional Comparison of Predisposing, Reinforcing and Enabling Factors for Lifestyle Health Behaviours and Weight Gain in Healthy and Overweight Pregnant Women

Objectives Little is known about the antecedents to dietary and physical activity behaviours that can support healthy gestational weight gain (GWG) across different weight status groups in pregnancy. The aim of this study was to use constructs common to dominant health behaviour theories to determine if predisposing, reinforcing and enabling factors for healthy eating, physical activity and weight gain differed between healthy and overweight pregnant women. Methods Pregnant women (n = 664) aged 29 ± 5 (mean ± SD) years were recruited at 16 ± 2 weeks gestation. Measures were self-reported pre-pregnancy weight, psychosocial constructs for healthy eating, physical activity and GWG and demographic data. Height was measured at 16 weeks. Psychosocial constructs were compared between women with pre-pregnancy weight status of healthy (BMI < 25 kg/m²) and overweight (BMI ≥ 25 kg/m²). Results Health behaviour intentions, positive outcome expectations and social support for healthy eating and physical activity were not different between healthy (66 %) and overweight (34 %) women. Overweight women had lower self-efficacy for healthy eating, physical activity and GWG (p < 0.001), higher negative outcome expectations for GWG (p = 0.004), and higher barriers to healthy eating (p = 0.002), and physical activity (p = 0.006). Conclusions for practice Both healthy and overweight women appear motivated to follow a healthy diet, exercise and avoid excess gestational weight during pregnancy. However many psychosocial factors associated with achieving these goals were different between healthy and overweight women. Health behaviour interventions tailored to overweight pregnant women should consider improving self-efficacy, providing support to overcome perceived barriers, validate positive changes made, and assist in managing negative expectations.

Influence of Nutrition Attitudes and Motivators for Eating on Postpartum Weight Status in Low-Income New Mothers

OBJECTIVE

The purpose of this study was to identify attitudes about nutrition and their influence on weight status in low-income mothers in the first year postpartum.

DESIGN

Nutrition attitudes were assessed at 1.5, 6, and 12 months postpartum. Body weight was measured at each time point and height at 1.5 months to calculate body mass index. Nutrition attitudes at each time were compared with demographic variables and weight status.

SUBJECTS

Subjects were 340 non-Hispanic white (31.3%), non-Hispanic black (25.1%), and Hispanic (43.7%) new mothers (mean age=22.4 years) located in central Texas. Criteria for participation included good health at delivery and low income (</=185% federal poverty guideline).

STATISTICAL ANALYSES

chi(2) tests were used to compare demographic groups to categorical variables. Multivariate analysis of variance was done to investigate the effect of demographic variables on instrument subscale scores. A repeated-measures analysis of variance was used to identify significant changes over time.

RESULTS

Obese women had higher barriers to healthful eating subscale means at 1 year compared with normal and overweight subjects at 1.5 and 6 months, and had more barriers than overweight participants at 12 months. Obese individuals also had higher emotional eating subscale scores than did overweight women at 1.5 months and both normal and overweight subjects at 12 months.

CONCLUSIONS

Women who were obese at 1 year postpartum were more likely to perceive more barriers to healthful eating and respond more to emotional cues to eat. Health professionals could emphasize potential changes and difficulties often faced in postpartum and identify techniques to overcome these obstacles to healthful eating.

Applying the theory of planned behavior to women's behavioral attitudes on and consumption of soy products

OBJECTIVE

To identify variables that significantly predict the intention and behavior concerning soy consumption applying the Theory of Planned Behavior and to determine the role of race on women's perspectives and consumption behaviors concerning soy.

DESIGN

Cross-sectional survey, with self-administered questionnaires.

SETTING

City park service programs, community organizations, black cultural classes, and university offices.

PARTICIPANTS

A convenience sample of 205 black (n = 103) and white (n = 102) women.

VARIABLES MEASURED

Women's behavioral attitudes, subjective norms, perceived behavioral control, intention, and behavior related to soy consumption.

ANALYSIS

Correlation and stepwise regression analysis.

RESULTS

All variables in the Theory of Planned Behavior showed significant correlations with behavioral intention, with behavioral attitudes exhibiting the strongest correlation (r = .57, P < .01). Stepwise multiple regression analyses revealed that behavioral attitude toward taste and subjective norms accounted for 47.7% of the variance in behavioral intention. Behavioral attitude toward taste explained 48.6% of the variability in behavior. There was no difference between races for consumption or Theory of Planned Behavior variables.

CONCLUSIONS AND IMPLICATIONS

A negative attitude toward the taste of soy was the major predictor for low soy consumption. However, future studies should be undertaken to verify this relationship once more women become aware of and have tasted soy.

Symposium on 'nutritional adaptation to pregnancy and lactation'. Pregnancy as a time for dietary change?

It is thought that nutrition during pregnancy plays a key role in the well-being of the mother and the newborn infant, and further influences health during childhood and adulthood. Pregnancy is a time of increased nutritional requirements, but many of these requirements will be met by adaptive physiological changes that occur during gestation, with little need to alter maternal dietary intake. A modest increment of food which provides 0.8 MJ/d (above prepregnant requirements) during the third trimester is considered adequate to meet the needs of fetal and maternal growth, and to satisfy the small increase in requirements of many macro- and micronutrients. However, requirements for vitamin D and folic acid increase substantially, and should be met primarily by supplementation. Food selection may also be altered to avoid a range of food-borne diseases and toxic constituents. There are a number of psycho-social reasons why pregnancy might be considered a good time for promoting changes in dietary behaviour for the health of the wider family. However, pregnancy may be a bad time to promote dietary change if it is perceived to involve slimming, if nutritional requirements are greatest before pregnancy, or if dietary changes made are harmful. There is little evidence to support educational interventions as successful at changing dietary behaviour during pregnancy. Pregnancy may be best viewed as an opportunity for maintaining good dietary selections and for building knowledge for future action, and should not be seen as the only opportunity for promoting dietary change within the life course.

UK consumer attitudes, beliefs and barriers to increasing fruit and vegetable consumption

OBJECTIVES

To assess attitudes, predictors of intention, and identify perceived barriers to increasing fruit and vegetable (F&V) intakes.

DESIGN

UK nationwide postal survey utilizing the theory of planned behaviour.

SUBJECTS

Stratified (by social class and region) random sample of 2020 UK adults providing a modest response rate of 37% (n = 741).

RESULTS

Belief measures (e.g. health, cost, taste, etc.) were strongly associated with overall attitudes which were reported as being largely favourable towards fruit, vegetables and, to a lesser extent, vegetable dishes, and were strongly associated with reported intention to increase consumption. Subjects reported they could increase their consumption, but this was only weakly associated with intention to do so. Approximately 50% of respondents reported an intention to increase intakes. Social pressure was strongly associated with reported intention to increase; however, scores indicated low perceived social pressure to change. Evidence of unrealistic optimism concerning perceived intakes and the perceived high cost of fruit may also act as barriers.

CONCLUSIONS

Results from this study suggest a lack of perceived social pressure to increase F&V intakes and suggests that public health efforts require stronger and broader health messages that incorporate consumer awareness of low present consumption.

The influence of dietary advice on nutrient intake during pregnancy

To assess the effect of an antenatal nutrition programme designed specifically for the local population, questionnaires on nutrition knowledge, attitudes to healthier eating and 4 d diet diaries were completed by women attending routine antenatal clinics. Women who received the nutrition education programme were allocated into an Intervention Education Group whilst those women who did not were allocated into a Routine Education Group. The results showed that knowledge about nutrition was significantly higher in the intervention group. However, no significant differences were detected between the two groups for attitude variables or nutrient intake. It is concluded, therefore, that the most-widely-read form of nutrition advice for pregnant women may have some impact on nutrition knowledge but has little effect on nutrient intake during pregnancy.
