Impact of Registered Dietitian Expertise in Health Guidance for Weight Loss

Abstract

Background & ObjectivesExpertise of registered dietitians (RDs) is important for health guidance but has been poorly evaluated. We evaluated the kind of RD expertise that would improve their skills.Design, Setting, Participants, MeasurementsThis study was a post-hoc analysis of our randomized controlled trial, which compared the weight change between participants using the web-based self-disclosure health support and those using the email health support. Healthy men and women aged 35–64 years with a body mass index (BMI) of > = 24.5 kg/m2 were recruited for this study. We evaluated the relationship of RD expertise indicators including the duration of working as an RD, the experience of health counseling, and membership in the Japan Dietetic Association (JDA) with the weight loss of study participants. The primary endpoint was the change in body weight. Comparison of changes in body weight by the RD expertise indicators was evaluated using analysis of covariance.ResultsA total of 175 participants were eligible for analyses. Changes in body weight were significantly greater when they were supported by the RDs in the routine counseling group than when supported by the RDs in the non-routine counseling group (-1.8 kg versus -0.4 kg, fully adjusted P = 0.0089). Duration of working as an RD and JDA membership did not significantly affect changes in body weight.ConclusionsAmong some indices of RD experience, the experience of providing routine experience of health counseling was associated with weight loss.

The use of whole body calorimetry to compare measured versus predicted energy expenditure in postpartum women

“…The development of personalized dietary recommendations relies on accurate assessment of energy expenditure in this population. Predictive energy equations may be used for individualized nutritional counseling, to assist women to achieve an optimal weight status through behavior change (13).…”

Exogenous dietary factors as important modulator of human lipid profile

“…Currently, the expertise of dietitians plays an important role in health guidance and improving the state of health: for example, it has been revealed that changes in body weight are significantly greater when patients were supported by dietitians during routine counseling than in the case of lack of such support. Additionally, the primary care outpatient clinic is an important source of information about healthy nutrition for patients, its influence on different biochemical laboratory parameters, especially on lipids and carbohydrate profile [42,43,44].…”

“…4 Birinci basamak sağlık hizmetlerinde obezitenin önlenmesi ve sağlıklı yaşamın sürdürülmesinde diyetisyenin rolü oldukça önemlidir. 7 Obezitenin etyopatogenezi kesin bir şekilde tanımlanmamış olsa da günlük gereksinimden fazla enerji alımı ve sedanter yaşam tarzının obezite gelişimindeki en önemli etmenler olduğu düşünülmektedir. Bu etmenler dışında; yaş, cinsiyet, öğrenim düzeyi, gelir durumu, sosyokültürel etmenler, genetik, metabolik bozukluklar, endokrin sorunlar ve psikolojik sorunların obezite gelişimi üzerinde doğrudan ya da dolaylı olarak etkilerinin olduğu belirtilmektedir.…”
