This study showed that nutritional knowledge, attitude and practice were higher after performance of nutritional educational program in addict patients (P < 0.0001). This finding indicates that drug addicts were successful in receiving nutritional information through the nutritional pogroms. In similar study, it showed there was association between nutritional risk and treatment retention. Given impact of nutrition on health for addicted is important aspect of drug treatment (
11). Most addicts have nutritional and metabolic disorders (
7,
12). Nutritional status of drug-addicted patients was very poor (
3).
Findings revealed satisfactory knowledge, positive attitudes and fair practice prevailed from this study. Educational interventional program was successful to improve nutritional behavior. The present study revealed that the mean score of knowledge (15.1 ± 6.1) was lower than the score obtained from after intervention (24.3 ± 7.5). This indicates higher tendency and awareness of addict patients to nutritional and health behaviors as well as self-care behaviors. In this study, as compared to before intervention a significant difference attitude of addicts (P < 0.0001) was found. They had a better nutritional attitude after intervention regarding nutritional and healthy behaviors. Generally, addict patients have many high-risk behaviors despite they usually have an unhealthy lifestyle (
1). According to the results of this study, the mean of nutritional attitude of patients was better than before intervention. This indicates that patients pay attention to health and self-care nutritional behaviors, which was mentioned in awareness section. In general, drug abuse is the result of interaction between the individual, substance, and environment. Knowledge and attitude of individuals toward drugs and drug effects is effective in its abuse. Some environmental factors involved in drug abuse are cultural factors, peer attitude toward drug abuse, parents' behavior, and regulations and policies, which restrict access to drugs (
1,
13). The results of the present study indicated a positive impact of nutrition education to improve addict patients' attitude, which can modify their life style. The findings also indicated that married people have better behavior and attitude compared to bachelors. The findings of this work showed that there was tendency to change behavior in addict patients regarding nutritional status. Therefore, it is possible to reduce the onset of risky behaviors. Today’s, drug abuse is considered as an undeniable problem in our society and it calls for realistic strategies to change nutritional attitudes and behaviors.
The mean of practice grade was (9.9 ± 2.8 vs.13.6 ± 3.9) including before and after intervention respectively (P < 0.0001). In this study, practice of addicts was promoted. There was a significant difference in the grade of knowledge, attitude, and practice of addict patients in different levels (poor, fair, and satisfactory) regarding gender, marital status, and education level after education (P < 0.0001). In the current study after intervention, according to demographic criteria such as gender, marital status, and education level, there was a significant difference in knowledge, attitude, and practice scores. Although, major factors in inclination to drug abuse include; familial conflicts, seeking pleasure, curiosity of adolescents, availability of drugs, peer pressure, parents' divorce, and lower levels of self-confidence (
1). This study showed that drug addicts are different regarding their nutrition. Therefore, they usually are nutritionally poor. It is necessary to ensure their nutritional condition through proper diet (
3,
14). Dietary choice and quality of nutrition should be evaluated in addicts. Nutrients are not consumed separately and they are a part of dietary intake; therefore, overall dietary intake should be evaluated for the assessment of nutritional status (
15). Our findings indicated that patients have a higher tendency to modify their life style. Results showed that patients pay more attention to their health and nutritional behavior that further study is needed.
Our study indicated that, after education nutritional knowledge of drug addicts was significantly improved. It was reported that attitude of addicted patients toward nicotine dependence treatment improved. While the interventional programmer likely had an effect, other factors could also have played a role in this apparent change in staff attitude (
16). However, it is possible that addicts are less willing to accept some habits as unhealthy behaviors regarding their own health (
17). Determination of nutritional knowledge, attitude and practice of patients can be effective to guide interventional strategies for healthcare of drug addicts. Drug habit affects nutritional status. At present, many efforts are made to encourage addicts to quit drug abuse. Other lifestyle factors associated with drug abuse having significant roles in their nutritional behavior include poverty, poor eating and exercise habits, lack of concern about nutrition and health, and diets restricted by physiological conditions (
1).
Efforts to quit by increasing the level of knowledge, offering health and nutritional information, giving nutritional education via addiction cessation program can increase the level of knowledge, attitude and promotion of their eating habits. This study indicated that nutritional KAP was improved in addicts. After intervention, there was a significant difference in the score of knowledge, attitude, and practice scores in patients in the current study. Improvements of KAP in patients after intervention were decreased KAP in poor level and increased KAP in fair and satisfactory levels. This finding indicates that addict patients would like to receive nutritional information through educational programs and modify their life style. However, the findings of following studies may uncover the real picture of nutritional behavior among addicts. It is recommended to use the capacity of addicts and performance of supporting and counseling programs in parallel to clinical treatment to decrease the duration of process of treatment and increase their recovery and rehabilitation.
