While nutrient supplementation addresses specific nutrient deficiencies buy 110mg sinemet visa, behavior change approaches can improve overall diet quality purchase sinemet 125mg fast delivery. Pregnancy is a period when women are more likely to improve their health behaviors. Thus, it is a time when unhealthy behaviors, such as smoking and poor diet, can be tackled and healthier behaviors promoted [48]. Changing the health behaviors of women preconceptionally is more challenging not least because this group of women might still be adolescents with little understanding of the influence of their own health on that of their babies. Women’s confidence, or self-efficacy, that they can make such changes is an important determinant of whether they will improve their health behaviors. Low levels of self-efficacy are common among women from disadvantaged backgrounds and mean that women are less likely to have healthy diets [49]. Many studies have demonstrated a relationship between higher levels of self-efficacy and better dietary behaviors [50]. Reviews of evidence have shown that interventions with certain features are more likely to improve health behaviors for disadvantaged women. These include: providing information on risks and benefits of health behaviors; goal-setting; and continued support after the initial intervention [51,52]. The evidence indicates that there is a need for empowerment approaches that work by improving the self-efficacy of participants. Evidence from trials during pregnancy also points to the effectiveness of behavior change approaches. These interventions led to improvements in diet although they did not improve the primary outcomes of gestational diabetes and babies born large for gestational age [53,54]. Importantly, both interventions included goal setting as a component suggesting that empowerment approaches are likely to be more successful in bringing about behavior change. The intervention, the Southampton Initiative for Health, aimed to improve the health behavior of women from disadvantaged backgrounds. These Centres were developed to provide services and support for women with children aged under five years with an initial focus on serving areas of disadvantage. Sure Start staff members come into contact with women and their children attending the Centres. The staff members were trained in skills to support behavior change: Healthy Conversation Skills [55]. As a result of the Healthcare 2017, 5, 14 8 of 12 training, staff changed the way they interacted with women, using open discovery questions, listening more than talking and empowering women to set goals. Evaluation showed that women who came into contact with trained staff had significantly smaller declines in their sense of control and self-efficacy than women in the control group, although an effect on diet was not observed [57]. Self-efficacy and sense of control are psychological factors known to be associated with diet quality among disadvantaged women. These findings suggest that the intervention could improve women’s health behaviors if it were delivered in a setting that allowed frequent contact between women and trained staff. Women access services during pregnancy, providing an opportunity for repeated exposure to the Healthy Conversation Skills intervention and a trial that is assessing the efficacy of the intervention during pregnancy in women who receive antenatal care in Southampton’s maternity hospital is currently underway. Changing the health behaviors of women preconceptionally is more challenging but, arguably more important than pregnancy as a period for prevention of later disease. One of the challenges is how to engage women in interventions preconceptionally and to find ways of sustaining their engagement in a way that is both acceptable and affordable. The behavior change skills (Healthy Conversation Skills) implemented in the Southampton Initiative for Health can be used by health and social care staff in a range of settings and have the potential to address the challenges of engaging women preconceptionally. The skills are easily-acquired and theory-based, and are designed for use in brief consultations, to support diet and lifestyle change. Engaging adolescents is likely to pose additional challenges since they are less likely than women of other ages to be in contact with routine health and social care. Teenagers aged 13–14 years, who attend Hampshire secondary schools, have three weeks of school lessons, supported by teacher professional development, and a visit to an educational facility in the local hospital. The aim of Lifelab is to improve young people’s health literacy and understanding of the long-term influences of their health behaviors on their subsequent health and that of their children [58]. In South Africa, for example, rates of obesity are high among adolescent girls leading to high rates of gestational diabetes and low birth weight. An intervention to reduce obesity among adolescent girls is being developed, that will use community health workers trained in behavior change techniques, to empower adolescent girls to improve their health behaviors [59]. Novel technologies also have potential for engaging adolescents in changing their health behaviors. Such interventions are becoming increasingly common, and there is some evidence of effectiveness [61] though surprisingly little of this evidence concerns adolescence.
