Abstract

Background: The use of complementary and alternative medicine (CAM) is becoming increasingly popular in Middle Eastern countries; it is often used for paediatric medical conditions such as chronic gastrointestinal complaints and failure to thrive. It is also commonly used in patients with chronic hepatic conditions such as cirrhosis and in hepatic transplant patients.

Aims: This study aimed to evaluate the prevalence, types and associated factors of CAM use in children with hepatogastrointestinal disease in Shiraz, Islamic Republic of Iran.

Methods: In a cross-sectional study carried out during September 2013–January 2014, 238 parents of children attending a paediatric gastroenterology and hepatology clinic at Shiraz University of Medical Sciences received a self-administered questionnaire covering associated factors of complementary and alternative medicine use; 210 questionnaires were completed and returned.

Results: Complementary and alternative medicine was used by 103 patients (49%); 74 (71.8%) of these used herbal remedies. Older age of the child significantly increased CAM use. Those with previous positive experience of CAM (62.1% of users, 40.2% of non-users) and those who had received recommendation for CAM by health care providers (24.3% of users, 6.6% of non-users) were significantly more likely to use CAM.

Conclusions: This survey demonstrated the high prevalence of CAM use (especially herbal remedies) in paediatric patients with hepatogastrointestinal diseases.

Introduction

Complementary and alternative medicine (CAM) covers a broad range of therapies that are outside conventional medicine (1). It is defined as “a group of diverse medical and health care systems, practices, and products that are not presently considered to be a part of conventional medicine “according to National Center for Complementary and Alternative Medicine in the United States of America (2). Recently, there has been a tendency toward using CAM (3). Several studies have evaluated the prevalence of CAM use and its associated factors in recent decades. Many have shown the noticeably prevalent use of CAM associated with factors such as age, race, socioeconomic status, education level, severity of disease and availability (4,5).

Several specific considerations are discussed on CAM use in paediatric patients. Ethical considerations due to inability of informed selection of therapeutic modality along with the narrow gap between therapeutic and toxic doses in paediatric patients make CAM use more challenging in this group.

The prevalence of CAM use in children has been reported as a wide range, from 10% to more than 80% of the study population (5–8), mainly due to different CAM definitions and study populations or different sample size (9). As an instance, among children with cancer, juvenile rheumatoid arthritis and cystic fibrosis, utilization of CAM is more prevalent (10). Some studies examined the use of CAM, comparing groups of children presenting with different diseases which leads to different results (5).

Among paediatric medical conditions, chronic gastrointestinal complaints and diseases such as chronic constipation, chronic abdominal pain and failure to thrive, along with patients with chronic hepatic diseases such as cirrhosis and hepatic transplant patients, are also disposed to high prevalence of CAM use (11). Use of CAM in these patients has specific considerations such as potential lower toxic doses and different herb and drug interactions in the absence of normal liver metabolism. These facts emphasize the need for more information on CAM use and associated factors in children with hepatic and gastrointestinal diseases.

This study aimed to evaluate the prevalence and type of CAM use in patients attending a paediatric hepatogastrointestinal clinic at Shiraz University of Medical Sciences. In addition, we attempt to describe child- and parent-related factors associated with the use of CAM.

Methods

Study design and sampling

We conducted a cross-sectional study on a convenience sample of 238 parents of paediatric patients presenting for health care visits at Shiraz University of Medical Sciences paediatric gastroenterology and hepatic referral clinic from September 2013 to January 2014. The study population was limited to parents of children with any gastrointestinal disease that were referred to the paediatric gastroenterology and hepatic clinic.

The study protocol was approved by the Medical Ethics Committee of Shiraz University of Medical Sciences (approval number: 90-5765).

Data collection

The researchers developed and piloted a survey on 20 parents (separate from the study group) to determine the information necessary to address the aims of the study.

Parents who were referred for their child to be visited by the paediatric gastroenterologist were invited to participate in this study. After signing the informed consent form, they filled out a self-administered questionnaire which took about 15–20 minutes to complete. Parents who for any reason were not able to express their ideas or filled out the questionnaires incompletely were excluded from the study. We designed the semi-structured questionnaire based on the current literature and our study goals. The questionnaire consisted of 16 questions including both open- and closed-ended questions, which were categorized into 2 domains. The first domain consisted of 9 questions regarding sociodemographic data such as child’s and parents’ age, parents’ education status, type of child’s disease and residence. The second domain consisted of 7 questions about the use of CAM within the last year, the type of CAM used, positive previous experiences about the beneficial effects of CAM, local access to CAM, the patient’s view about possible interactions of CAM with chemical drugs.

It was necessary for us to mention popular types of CAM that are practised among Iranian people to better define CAM for participants. Also, the patients’ parents determined the type of disease for which CAM is used (e.g. abdominal pain, constipation, jaundice, diarrhoea, reflux and inflammatory bowel disease), type of CAM used, previous recommendations or prohibition by their health care providers, previous positive or negative experience with CAM and their access to CAM providers

Statistical analysis

Descriptive statistics were used to characterize the study participants overall and within subgroups. Bivariate comparisons of the user and non-user groups were made using the Chi-squared test for categorical variables and the t-test for continuous variables. P values < 0.05 were considered statistically significant.

Multiple logistic regression analysis was undertaken to determine the independent association between CAM use and the multivariate predictors. Selected variables in the logistic regression model were based on the analysis of each variable using Chi-squared and the independent t-test. If the P value was ≤ 0.25, the variable was then examined using logistic regression.

Results

From 238 questionnaires distributed, a total of 210 (88.23%) were completed. Twenty eight patients (11.76%) were excluded from the study because they refused to complete the questionnaires or filled out the questionnaires incompletely.

The mean age of the paediatric patients was 6.2 [standard deviation (SD) 4.9] years (range 1 month–19 years) and the mean age of the mothers and fathers was 31.6 (SD 6.35) years (range 23–68 years) and 36.3 (SD 7.58) years (range 18–51 years) respectively. Patients presented with a variety of diseases, including gastrointestinal diseases (46.6%), hepatic diseases (31.1%) and failure to thrive (6.8%) (Table 1).

Details of sociodemographic characteristics of the participants and associated factors in CAM users versus non-users are shown in Table 1.The use of CAM was not influenced by the parents’ attitude about side-effects (P = 0.063) nor their attitude about the results of the combination of CAM with routine drugs (P = 0.195).

One hundred and three patients (49%) used CAM in the course of their hepatogastrointestinal disease; 74 (71.8%) used herbal remedies and 46 (44.6%) used other types of CAM (Table 2). Spiritual therapy was sued by 35.9%. It should be noted that the patients were allowed to choose more than one option, so the summation of values may total more than 100%. Among the herbal remedies, the most common ones used in hepatogastrointestinal diseases by the study population are shown in Table 3. Descurainia sophia (33%) and Thymus vulgaris (16%) were the 2 most commonly mentioned.

No significant difference in the rate of CAM use was observed among patients with different parents’ ages (P = 0.35 and P = 0.09 for mothers and fathers respectively) (Table 2), but logistic regression analysis showed that older age of the child significantly increased CAM use (OR 0.08; P = 0.036) (Table 4).

Patients with previous positive experience of CAM (62.1% of users vs 40.2% of non-users, P = 0.046) and patients who had received recommendation for CAM use by health care providers (24.3% of users vs 6.6% of non-users, P = 0.001) were significantly more likely to use CAM than others according to logistic regression analysis (Tables1,4). But prohibition of CAM use by health care providers did not significantly affect the prevalence of CAM use (20.4% of users vs 20.6% of non-users, P = 0.97).

Discussion

Our findings demonstrated the prevalence and associated factors of CAM use in paediatric patients referred to Shiraz University of Medical Sciences paediatric hepatogastroenterology clinic. This study showed that 49% of the patients used at least 1 type of CAM. Herbal remedies were the most common type used. Older child age was associated with the use of CAM. Additionally, the patients who were advised by their health care provider to use CAM and those who had previous positive experience with CAM were more likely to use it.

Complementary and alternative medicine is commonly used in the Iranian population, especially herbal medicine (12,13). Several studies have been done on the pattern and associated factors of CAM use in different diseases, and prevalence ranged from 10% to 67%. This wide range was influenced by differences in the population samples and types of CAM (14–18).

To the best of our knowledge, although there has been no study that evaluated the prevalence and type of CAM used in paediatric patients with hepatogastrointestinal diseases in Iran, the prevalence rate of CAM use in our study was similar to the findings of Tonekaboni et al. for epileptic children in Tehran (17). They reported a 44% prevalence of CAM use. Additionally, our result on the use of CAM is similar to those of 2 studies conducted in Turkey and Switzerland. Arýkan et al. in their survey on children with type I diabetes demonstrated CAM use by 52% of them (19). Moreover, Zuzak et al. reported 58% CAM use in a population of paediatric patients presenting to an emergency department (20).

However, our results are in contrast with those of several other studies on paediatric patients. For example, 19% of parents of children with type I diabetes at an American urban paediatric clinic reported CAM use for their children (21). Another study in a primary paediatric care centre in Washington DC reported CAM use in 21% of children (22). Also, a survey in a general paediatric clinic reported a lower CAM use (30%), in contrast to our findings (23).

As in previous Iranian research on prevalence of CAM use (24), herbal remedies were the most common form, (71.8%) of CAM use in our study. However, some investigations on CAM use for paediatric patients reported herbal medicine use by 40–60% of CAM users (19,21–23). Spiritual therapy was another common type of CAM reported in our study. This is probably due to the religious beliefs which are very common in Iranian culture.

Live raw fish swallowing was a traditional remedy in Iranian folklore medicine for treatment of paediatric jaundice (25). This folk habit was also reported to be used in other countries (26) and is associated with the risk of parasitic infections (27).

Among the herbal remedies used, Descurainia sophia is one of the most common herbs used in Traditional Persian Medicine as a neonatal jaundice remedy (28–30). Although we did not find any study about the relationship between D. sophia and jaundice, some research that showed anti-inflammatory and laxative effects of D. sophia (31,32). Thymus vulgaris is another plant used frequently by patients, especially for abdominal pain. The antispasmodic and gastrotonic effects of this plant are supported by previous studies (33,34). Taranjabin, or Persian manna, and Cotoneaster are traditional laxatives used commonly in paediatric patients (35), and are traditionally used in the management of neonatal jaundice. Some clinical studies support the efficacy of these herbs in the treatment of neonatal jaundice (36–38). However, according to the most famous resources of Traditional Persian Medicine, such as the Canon of medicine by Avicenna (980–1037 AD) (39), and the Liber continens of Rhazes (865–925 AD) (40), there is no scientific support for some of these uses.

The reasons for the use of medicinal herbs by the Iranian population are clear. Briefly, several investigations indicate their relative efficacy in some traditional uses. Also, Traditional Persian Medicine has a long history and there are inextricable relationships with the daily life of Iranian people (41). Accessibility and the relatively low cost of medicinal herbs are among the other reasons for their use (42).

This study showed a slight but statistically significant positive association between the child’s age and use of CAM. Previous studies also showed a higher prevalence of CAM use in adult populations than paediatric populations (43–45). Also, according to a study by Ottolini et al., older children were treated with CAM more than younger ones (22). This lower frequency of CAM use in children, especially the younger ones, may be due to parental considerations about the potential adverse events of herbs on smaller children.

Our study had some limitations. It was not a population-based survey and our results are not generalizable to the entire population. Moreover the sample size was not large enough to be really representative of the population variations. Lack of a validated questionnaire is a common methodological problem in the most surveys like ours (9). Another consideration in interpreting our results is that supplements (vitamins, probiotics and fish oil) were not considered as CAM in our study.

As a conclusion, this study demonstrated a high prevalence of CAM use, particularly herbal remedies, in paediatric patients with hepatogastrointestinal diseases, which was independently and significantly associated with previous positive experience, healthcare providers’ recommendation and older age of the child.

Utilisation des médicaments complémentaires et alternatifs chez les patients pédiatriques atteints de maladies hépato-gastro-intestinales

Résumé

Contexte : L’utilisation des médicaments complémentaires et alternatifs (MCA) est de plus en plus populaire dans les pays du Moyen-Orient. Ils sont souvent employés pour traiter les problèmes médicaux pédiatriques tels que les troubles gastro-intestinaux chroniques et les retards staturo-pondéraux. Elles sont aussi couramment utilisées chez les patients atteints de maladies hépatiques chroniques telles que la cirrhose et chez les patients ayant reçu une greffe de foie.

Objectifs : La présente étude avait pour objectif d’évaluer la prévalence de l’utilisation des médicaments complémentaires et alternatifs ainsi que les types de médicaments et les facteurs associés chez les enfants souffrants de maladies hépato-gastro-intestinales à Chiraz, en République islamique d’Iran.

Méthodes : Dans une étude transversale réalisée entre septembre 2013 et janvier 2014, 238 parents d’enfants consultant dans une clinique d’hépatologie et de gastro-entérologie pédiatrique à l’Université des Sciences médicales de Chiraz ont reçu un questionnaire auto-administré couvrant les facteurs associés à l’utilisation des médicaments complémentaires et alternatifs ; 210 questionnaires ont été remplis et renvoyés.

Résultats : Des médicaments complémentaires et alternatifs étaient utilisés pour le traitement de 103 patients (49 %) ; 74 (71,8 %) d’entre eux utilisaient des remèdes à base de plantes. Ces médicaments étaient beaucoup plus utilisés chez les enfants plus âgés. Les répondants ayant eu des expériences précédentes positives avec des médicaments complémentaires et alternatifs (62,1 % d’utilisateurs, 40,2 % de non-utilisateurs) et ceux à qui des prestataires de soins de santé avaient recommandé ces médicaments (24,3 % d’utilisateurs, 6,6 % de non-utilisateurs) étaient beaucoup plus susceptibles d’utiliser les médicaments complémentaires et alternatifs.

Conclusions : La présente étude a montré la forte prévalence de l’utilisation des médicaments complémentaires et alternatifs (en particulier les remèdes à base de plantes) chez les patients pédiatriques atteints de maladies gastro-intestinales.
