RESUMO

To address the prevalent genistein (GST) metabolism and inadequate intestinal absorption, an oral long-acting and gastric in-situ gelling gel was designed to encapsulate and localize the intestinal release of the loaded genistein-ginseng (GST-GNS) solid dispersion. Because of the high breast perfusion of GST upon oral absorption, the GST-GNS solid dispersion was developed to enhance GST's dissolution and penetration while offering a synergistic impact against breast cancer (BC). Physiochemical analysis of the GST-GNS solid dispersion, release analysis, gel characterizations, storage stability, penetration, and in vitro cytotoxicity studies were carried out. GST-GNS solid dispersion showed improved dissolution and penetration as compared to raw GST. GST-GNS solid dispersion homogenous shape particles and hydrophilic contacts were revealed by scanning electron microscopy and Fourier Transform-Infrared analysis, respectively. GST-GNS solid dispersion's diffractogram shows the amorphous character. A second modification involved creating a gastric in-situ gelling system loaded with GST-GNS solid dispersion. This system demonstrated improved GST penetration employing the solid dispersion, as well as the localizing of the GST release at the intestinal media and antitumor synergism against BC. For a better therapeutic approach for BC, the innovative oral GST long-acting gel encasing the GST-GNS solid dispersion would be recommended.

RESUMO

This study was designed to investigate the level and associations of physical activity, sedentary behavior, sleep, and dietary habits among Saudi women attending fitness centers in Riyadh. A descriptive cross-sectional study was carried out from 12 fitness centers in Riyadh, Saudi Arabia. A total of 460 participants answered a two-part survey self-administered questionnaire, which included information about the demographic characteristics and lifestyle. The analysis found significant differences between the two groups in terms of age, weight, BMI, and combined prevalence of being overweight and obese. Compared with less active females, high active females showed significantly more favorable dietary habits (p < 0.05). Significantly higher values were observed for the total physical activity energy expenditure in METs-min/week (p = 0.028). Moreover, females with high screen time (>3 h per day) were younger, less active, slept longer, and had higher intakes of fast foods and chocolates/candy intake (p = 0.001). Overall, the participants were highly active, exceeding the recommended physical activity needed to enhance health. The analysis also showed sufficient sleep duration (>7 h/night) was significantly associated with the diet and nutrition of the participants. Health education programs are needed to reduce the risks of sedentary behavior, sleep problems, and dietary habits.

RESUMO

OBJECTIVE: To examine body image perception and the associations of body dissatisfaction (BD) with socio-demographic and lifestyle factors among Saudi women attending fitness centers in Riyadh. METHODS: Saudi females aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using stratified clustered sampling technique (n = 460). Height and weight were measured to calculate actual body mass index (BMI). A previously validated instrument was used to collect socio-demographic and lifestyle variables including physical activity (PA), sedentary behaviors, sleep and dietary habits. Stunkard Figure Rating Scale silhouettes were used to assess perceived and desired body shape. RESULTS: The participants had a mean (SD) age of 29.2 (8.2). The majority were not married (57%), with no children (66%) and had college degrees (78%). While 63% were overweight or obese, nearly 40% of women underestimated their perceived body shape. The majority of respondents (87%) were dissatisfied with their body shape including 68% of normal weight women. Females who had BD were significantly older, had higher BMI, reported more weight loss attempt and had expended less time in vigorous (p = 0.033) and total (p = 0.042) PA than those who were satisfied with their body shape. However, when adjusting for socio-demographic variables, logistic regression analysis revealed significant associations of BD with higher BMI, shorter membership duration of fitness club, and reduced dairy products and energy drinks consumption. CONCLUSION: Except for BMI and decreased dairy products and energy drinks consumption, many lifestyle behaviors did not associate with BD among Saudi females attending fitness centers. The findings can inform healthcare providers when intervention strategy is implicated for females with BD. Future studies should compare the associations of BD with lifestyle behaviors between males and females attending fitness centers and seeking weight loss.

RESUMO

OBJECTIVE: To examine the associations of overweight or obesity with several lifestyle and socio-demographic factors among Saudi women attending fitness centers in Riyadh. METHODS: Saudi females (n = 460) aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using a stratified clustered sampling technique. Bodyweight and height were measured. Lifestyle behaviors were assessed using a previously validated instrument, and included physical activity, sedentary behaviors, sleep, and dietary habits. RESULTS: Over 62% of the participants were either overweight or obese. Mean BMI values for females younger than age 30 years (26.4 ± 5.3) were significantly lower than those 30 years of age or older (29.2±5.6, p >0.001). There was a significant correlation (r = 0.450, p < 0.001) between BMI levels and the participant's reason to engage in exercise for weight loss. Females who were overweight/obese are significantly older, married, have more children, have a lower educational degree, earn less income, have higher numbers of obese in the family, and had attempted to lose weight more frequently than non-overweight/non-obese females. No significant differences were detected between females who were overweight/obese and those who were not overweight/obese in the majority of the lifestyle-related variables, except that females who were not overweight or obese showed lower weekly consumption of milk and dairy products (p =0.029) and higher intakes of fast foods per week (p =0.049). CONCLUSION: Weight loss attempts, age, number of obese in the family, and females' education level emerged as the most important contributory factors to obesity status, explaining nearly 23% of the common variances. A better understanding of the relationships between obesity and lifestyle behaviors is necessary for effective prevention and management of obesity in Saudi females.
