Acne Vulgaris and adherence to the mediterranean diet among university students: a case‒control study

BACKGROUND

Western diets, characterized by a high glycemic index and dairy content, can be risk factors for acne vulgaris. A few studies have suggested that adherence to non-Western diets, such as the Mediterranean diet (MD), may be protective against acne. This study aimed to explore the relationships between adherence to the MD and acne diagnosis and severity.

METHODS

This was a matched case‒control study carried out among university students studying health sciences to explore the relationship between adhering to the MD and an acne diagnosis. Convenience sampling was utilized for the initial recruitment of eligible participants, who were then 1:1 individually matched for age, gender, and body mass index (BMI). Adherence to the MD was assessed using the Mediterranean Diet Adherence Screener (MEDAS) tool, and acne severity was assessed using the Global Acne Grading System (GAGS). The data were analyzed using descriptive statistics, bivariate analysis, and conditional logistic regression, which included two models based on clinical data and the backward elimination technique.

RESULTS

A final sample of 121 cases was individually matched to 121 controls. Each group consisted of 28.9% males and 71.1% females, with most having a BMI within the healthy range (71.9%). Both the case (80.2%) and control groups (77.7%) demonstrated a predominant pattern of low adherence to the MD. At the bivariate level, family history significantly differed between the case and control groups (OR = 2.01, CI = 1.17-3.44), while adherence to the MD (OR = 0.86, CI = 0.46-1.60) did not reach statistical significance. According to the regression analysis, family history remained significant in the backward elimination model (aOR = 1.94, CI = 1.14-3.34), while it disappeared in the full model (aOR = 1.95, CI = 1.14-3.34). Neither model revealed a significant association between acne and the other variables. Among the participants in the case group, neither adherence to the MD nor adherence to its components was significantly associated with acne severity, except for vegetables (p = 0.022).

CONCLUSIONS

Adherence to the MD was not correlated with acne diagnosis or clinical severity. More research on the association between acne and adherence to the MD is needed, as earlier studies are few, were conducted in specific settings, and used variable methodologies. To improve the validity and reliability of the research methodology, the development of detailed and culturally adapted MD definitions and practical guides is recommended.

Prevalence of acne and its impact on quality of life and practices regarding self-treatment among medical students

Acne vulgaris is one of the most common skin diseases worldwide and causes great distress to patients. In addition, most acne patients suffer from low self-esteem and social withdrawal. This study aimed to assess the prevalence of acne and its impact on quality of life among medical students. It also evaluates the patterns of self-treatment use. The study population consisted of all medical students from An-Najah National University (ANU) and the hospital. The questionnaire consists of three parts, and the first part consists of questions regarding demographic information. The second part consisted of questions to measure the severity of acne using the acne severity scale as well as the Cardiff Disability Index, which assesses the quality of life concerning acne in medical students. Finally, the third part consisted of questions exploring and assessing acne self-treatment. The mean age of our study sample was 21.3 ± 1.9 years, with a female predominance of 72.3%. The prevalence of acne among medical students was 80.9%, and 36.6% practiced self-medication. Acne was strongly associated with female sex (p < 0.001) and skin type (p = 0.024). Regarding diet, dairy consumption (p = 0.007), sweets (p < 0.001), chocolate (p < 0.001), and oily food (p = 0.006) were all significantly associated with acne. Skin type was strongly associated with the severity of acne (p < 0.001) and the Cardiff acne disability index (p = 0.016). Gender (p = 0.039) was also associated with Cardiff acne disability. A significant correlation was found between the severity of acne and impaired quality of life. The most commonly used topical agent for self-treatment remedies was antibiotics (70.3%). The most commonly used oral agent was isotretinoin (9.4%). A total of 22.7% of the students used herbal products, while 47.7% used home remedies. Acne is prevalent among medical students, with a high percentage of students having different degrees of impairment in their daily lives. As a result, self-medication among acne sufferers is highly common. Awareness of the appropriate use of self-medication should increase among medical students.

Assessment of body image disturbance, self-esteem and quality of life among adolescents and young adults with acne in a tertiary care facility of India

Background:

Impact of acne on the psychological aspect among adolescents and young adults is poorly understood and many times goes unnoticeable.

Aim:

To assess body image disturbance, self-esteem, quality of life among adolescents and young adults with acne.

Materials and Methods:

A cross sectional survey on 250 adolescents and young adults aged 13-25 years in Dermatology OPD of a tertiary care hospital, was performed. Severity of acne, body image disturbance, self-esteem, and quality of life were assessed using standardized tools like IGA scale, BIDQ, RSES, and TAQOL respectively.

Results:

A majority of the participants, 163 (65%), were aged 20–25 years, in which 141 (56.4%) were male, 237 (94.8%) were unmarried, 192 (76.8%) were residing in urban area, 142 (56.8%) were graduate/post-graduate, 173 (69.2%) were students and 113 (45.2%) belonged to upper middle class of socio-economic status. More than half, 137 (54.8%), had a family history of acne, 228 (91.2%) had oily skin, 166 (67.4%) had normal nutritional status, 154 (61.6%) had moderate form of acne whereas 80 (32%) had severe acne. The mean BIDQ score was 3.05 (SD = 0.89); 169 (67.60%) had normal self-esteem and 174 (69.64%) had mild impairment in quality of life. Severity of acne had significant association with body image disturbance (P = 0.007) and quality of life (P = 0.001) but not related with self-esteem.

Conclusion:

The results revealed body image disturbance and impaired quality of life among adolescents and young adults with acne which draws the attention of dermatologists towards unidentified psychological aspects of acne during treatment. However, the majority of them revealed normal self-esteem in the study.

Epidemiology of acne vulgaris in adolescent male students in Arar, Kingdom of Saudi Arabia

BACKGROUND

Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Small, noninflamed acne lesions may not be more than a slight nuisance, but, in individuals with more severe inflammatory disease, pain, social embarrassment, and both physical and psychological scarring can be life altering. Despite its high prevalence, no previous community-based studies have been conducted in Arar, northern border of Kingdom of Saudi Arabia, addressing this issue.

OBJECTIVES

The aim of this study was to estimate the prevalence of acne vulgaris, to describe the sociodemographic characteristics of cases, and to determine the aggravating factors and the psychological impact of acne vulgaris in a representative sample of secondary school male students in Arar city, Kingdom of Saudi Arabia.

PATIENTS AND METHODS

This was a cross-sectional study. A multistage systematic random sampling technique was followed. A total of 400 male students during the academic year 2015-2016 were included in the study. Data were collected by means of personal interview and filling-in a questionnaire.

RESULTS

The overall prevalence of acne vulgaris was 53.5%. The mean age of onset was 15.0±1.2 years. Positive family history of acne vulgaris was found in 46.7% of cases. The skin was greasy in 61.7% of cases. Acne site was the face in 67.3%, the back in 4.7%, and both in 28% of the cases. More than half (54.2%) of the cases had first-degree acne. Students mentioned several factors affecting the appearance of acne; 59.8% of cases reported a relation of increased acne appearance with the cleanliness of the skin, 35.5% reported relation with consumption of fatty meals, 24.2% with eating chocolate, 23.3% with consumption of spicy food, 12.1% with excess intake of cola drinks, 31.8% with heavy smoking, and 60.7% reported increased acne appearance in summer months.

CONCLUSION AND RECOMMENDATIONS

Acne was highly prevalent among secondary school male students in Arar city, Kingdom of Saudi Arabia. Several risk factors increased the appearance of acne, including, skin cleanliness, certain diets, and smoking. There was clear seasonal variation, with a higher prevalence mainly in summer. Therefore, community-based multiple strategies are required to combat with increasing rate of acne vulgaris and its subsequent complications among adolescents in Arar city and to educate them about its causes and the risk factors for its development.
