Nutritional status changes in the treatment of substance use disorder: Relationship with substance craving

Tailored nutrition counseling enhances the efficacy of routine treatment for substance (alcohol/drugs) use disorders (SUDs). For this purpose, it is important to understand the current nutritional status of addicts and the changes in their nutritional status during the treatment process. Furthermore, the consumption of sweets to manage substance cravings is common among people with SUDs, but the evidence for the effectiveness of this practice is limited and conflicting. We therefore hypothesized SUD treatment would be associated with increases in appetite, nutrient intake, and anthropometric measurements in addicts, and that these changes, including changes in sweet consumption, would not be associated with decreased substance craving. Data for this prospective observational study were collected from 38 adult male patients who completed 21 days of inpatient SUD treatment. During the treatment, the participants' levels of appetite (P < 1.0 × 10^-4), the frequency of main meals (P < 1.0 × 10^-4), intake of macro- and micronutrients (P < .05 for each), and anthropometric measurements (P ≤ 5.9 × 10^-4), significantly increased. Furthermore, it was found that the patients had a significant increase in sweets craving (P < 1.0 × 10^-4) and sweets consumption (P = 1.2 × 10^-3) during treatment. However, there was no significant difference between the individuals whose craving decreased and those whose craving did not decrease at the end of the treatment (P > .05 for both). The findings suggest the need to offer dietary counseling to individuals undergoing inpatient SUD treatment, given the substantial changes in nutritional status, and that increased consumption of sweets is not an effective strategy to reduce substance craving.
