The Use of Weight Loss Products and Body Mass Index among University Students in Kota Bharu, Kelantan (Penggunaan Produk Penurunan Berat Badan dan Indeks Jisim Tubuh dalam Kalangan Pelajar Universiti di Kota Bharu, Kelantan) / Jurnal Sains Kesihatan Malaysia

@#Body mass index (BMI) was one of the reasons people used weight loss products to lose weight. The purpose of this study is to look into the use of weight loss products and their relationship to BMI and associated factors. A cross-sectional study with convenient sampling was conducted on 133 students from Universiti Sains Malaysia, Kubang Kerian (USMKK) Health Campus. Participants were asked to complete an online questionnaire that included sociodemographic information, self-reported weight and height for BMI, weight loss product use, weight loss product usage characteristics, body weight perception and satisfaction, and weight loss product perception. The majority of participants were female (78.2%), 80.5% were Malay, and the mean age was 22 ± 3.1 years old. Majority had a normal BMI (56.4%), whereas 16.5% were underweight, 18.8% were overweight, and 8.3% were obese. Nevertheless, only 10.5% of participants utilised weight loss products. It was discovered that the use of weight loss products is statistically associated with BMI, with a high proportion of users having an overweight or obese BMI (p=0.042). Those who reported using a weight loss product had a higher BMI [25.56 (IQR 6.6) kg/m2 ] than those who did not [21.35 (IQR 5.3) kg/m2 ] (p = 0.015). The use of weight loss products was also statistically associated with perceived product safety (p=0.041) and body weight dissatisfaction (p=0.011). Universities should therefore provide students with appropriate weight loss advice, up-todate information on the safety and efficacy of various weight loss products, and opportunities to enhance their knowledge, self-efficacy, and social support. For future research, it is suggested to wider the research population to overweight and obese adults in Kelantan.

Body Mass Index, Body Weight Perception, and Depressed Mood in Korean Adolescents

OBJECTIVES: We examined the relationships between the body mass index, body weight perception, and depressed mood in a nationally representative sample of Korean adolescents. METHODS: We analyzed the data from the 2013 Korean Youth Risk Behavior Web-based Survey and evaluated the relationships between the body mass index, body weight perception, and depressed mood by gender (36655 boys and 35780 girls). RESULTS: For boys, a low body mass index and perceiving oneself as underweight were related to depressed mood. For girls, both low and high body mass indices were negatively related to depressed mood. In addition, self-perceptions of being underweight or overweight were positively related to depressed mood. Body weight perception was not a significant mediator in the relationship between body mass index and depressed mood. CONCLUSION: These results suggest that both body mass index and body weight perception significantly contribute to Korean adolescents' depressed mood. Thus, research and clinical attention needs to be given to underweight as well as overweight adolescents, because those who perceive their weight as not normal are at risk for depression.

Gender Differences in Body Image Perception among Northern Malaysian Tertiary Students.

Aims: This study examined the association of socio-cultural and psychological factors with body shape concern, perception and body weight perception among tertiary students of Northern Malaysia. Study Design: This is a cross-sectional study. Place and Duration of Study: Universiti and Kolej Tunku Abdul Rahman (UTAR and KTAR), Perak campuses, between August 2011 and January 2012. Methodology: A total of 1003 students were recruited (M = 431, F = 572; mean age 19.96 ± 1.51) and their body image perception were assessed using Body Shape Concern Questionnaire, Body Weight Perception Questionnaire, Body Shape Perception Questionnaire (Stunkard Silhouette Chart), Multidimensional Body Self Relations Questionnaire (MBSRQ), Rosenberg’s Self-Esteem Scale (RSE) and Quality of Life measurement. Results: More females than males had problems with their body shape, where more females desired a thinner body size and vice versa for males. There was misperception of opposite sex’s perception of attractive body shape, where males chose a larger figure for attractive body shape of female compared to females themselves, and vice versa. Overweight students had significantly lower parental/peer acceptance, higher body shape satisfaction and hence lower body weight/shape anxiety, and made lesser body shape comparison compared to other counterparts. Quality of life and self-esteem were significantly negatively correlated with body satisfaction. Conclusion: Male and female Malaysian tertiary students were concerned with their body shape and perceived their body weight/shape differently.

Gender Differences in Body Mass Index, Body Weight Perception and Weight Loss Strategies among Undergraduates in Universiti Malaysia Sarawak

Introduction: This study was carried out among undergraduate students in Universiti Malaysia Sarawak with the objective of examining gender differences in body mass index (BMI), body weight perception, eating attitudes and weightloss strategies. Methods: Subjects consisted of 600 undergraduates (300 males and 300 females) recruited from the various faculties between September 2008 until mid-November 2008. The Original Figure Rating Scale: Body Weight Perception, Body Shape Questionnaire (BSQ) and Eating Attitudes Test-26 (EAT- 26) were used as assessment tools. Results: Overall, 52.8% of students had normal BMI, with approximately an equal number of both sexes. More males than females were overweight (33.7%), while more females were underweight (25.3%). Males were more likely to perceive themselves as overweight, and fail to see themselves as underweight. More than half of the females preferred their ideal figure to be underweight, whereas about 30% males chose an overweight figure as their ideal model. Females were generally more concerned about body weight, body shape and eating than males. They diet more frequently, had self-induced vomiting, and used laxatives and exercise as their weight-loss strategies. Conclusion: Issues pertaining to body weight perception, eating attitudes and weight-loss strategies exist with differences among male and female undergraduates. Thus, in order to correct misperceptions among young adults, a more tailored intervention programme and more in-depth studies into the various factors involved are required.

Percepción del peso corporal y estrategias utilizadas para controlarlo, en adultos costarricenses / Body weight perception and strategies used to control body weight among Costa Rican adults

Justificación: La obesidad se considera un problema de salud pública. La encuesta directa es el método más utilizado para generar información al respecto, pero su alto costo económico limita obtener datos periódicos. Se han experimentado otros métodos de recolección de información; entre ellos la encuesta telefónica se concibe como una opción válida de costo menor. Objetivo: Explorar la percepción del peso corporal de adultos costarricenses y las estrategias utilizadas para controlarlo, mediante el análisis de la información obtenida en la primera Encuesta Telefónica de Salud del IDESPO. Métodos: Estudio descriptivo, transversal. Se elaboraron preguntas abiertas sobre conocimiento, percepción y estrategias sobre peso corporal, que se incorporaron en la primera Encuesta Telefónica de Salud del IDESPO. Resultados: El 50,3 por ciento y 42 por ciento de los sujetos se percibieron con peso normal y peso alto o muy alto, respectivamente. Las principales estrategias para perder el peso: hacer ejercicio, 29,4 por ciento, cambios en la alimentación; 42 por ciento de los hombres y 44 por ciento de las mujeres reportaron "no hacer nada". Al contrastar la percepción del peso con el IMC estimado, más del 25 por ciento de mujeres y 34 por ciento de hombres que se percibieron con peso normal presentaron sobrepeso. Conclusiones: La metodología de encuesta telefónica introduce una subestimación en la percepción del exceso de peso conforme avanza la edad. La encuesta telefónica no sustituye las encuestas directas, pero se visualiza como alternativa para generar información sobre factores de riesgo cardiovascular. El reto próximo será validarla en nuestro contexto.

Rationale: Obesity is considered a public-health problem. A direct survey is the method most-frequently used to generate relevant information but its high economic cost doesn´t allow obtaining periodic data. Other methods of collecting information have been tried and, among these, the telephone survey is seen as a valid option at lower cost.Objective: To explore the perception of body-weight among Costa Rican adults as well as the strategies used to control this variable by analyzing information obtained in the First Telephone Health Survey conducted by IDESPO (The Institute for Social Studies in Populations.) Methods: a cross-sectional, descriptive study was carried out. Open questions were developed having to do with knowledge, perception and strategies to deal with body-weight. These were incorporated into the Health Survey mentioned above.Results: 50.3 % and 42% of the subjects, respectively, had a self-perception of normal weight or of high - very high weight. The main weight-loss strategies were: doing exercise (29.4%), changes in diet and no special strategy (the latter as admitted by 42% of men and 44% of women). When comparison of self-perception of weight with estimated BMI was done, more than 25% of females and more than 34% of males of those thinking they had normal weight were actually overweight. Conclusions: a telephone-survey methodology introduces an underestimate in the self-perception of overweight according to age. While telephone surveys do not substitute direct surveys, they can be seen an an alternative to generate information about cardiovascular risk factors. The next challenge will to validate these surveys in Costa Rica.
