This study was conducted to assess the students’ perception of difficult topics in mathematics in some selected senior secondary schools (SS) in Kano state Nigeria. Two hundred (200) SS final year (III) students were randomly selected from ten (10) selected senior secondary schools within Bichi zone of Kano state Nigeria. A twenty items questionnaire was administered to respondents. Mean, standard deviation, and independent sample t-test statistics were used to analyze the data. Findings revealed that students perceived 13 topics (65%) difficult to comprehend. The study also showed that students’ gender had a significant influence on their perception of difficult topics in mathematics [t (198) =2.34, P =0.020, α = .05] and the nature of students’ schools had no significant influence on their perception of difficulty in mathematics [t (198) = -.444, p = 0.657, α = .05]. It was recommended that students should be encouraged and motivated to learn mathematics, curriculum developers should develop instructions that would improve students’ knowledge by laying more emphasis on the perceived difficulty areas in mathematics and further studies should be conducted to find out the factors responsible for the perceived difficulty and also if there is a relationship between perception and students’ achievement.

Our goal was to determine food cravings, nutritional status and physical activity of patients diagnosed with major depression. The study was conducted on 203 (144 women, 59 men) patients, aged 20-64 years, who were diagnosed with major depression at three psychiatry centers. Anthropometric measurements, demographic data, current health status, depression duration, drug use, eating habits, food craving status (Food Craving Questionnaire-Trait/FCQ-T), food consumption frequency, energy and nutrient intake and physical activity level (International Physical Activity Questionnaire-Short Form/IPAQ) were evaluated. Depression duration, the frequency of antidepressant use and FCQ-T scores were higher in females than males. We found a positive correlation between FCQ-T score with the frequency of antidepressant use, depression duration and eating speed  (p < 0.05). Also, depression duration was negatively correlated with folate, vitamin B6, vitamin C and zinc (p < 0.05). Lastly, depression duration and FCQ-T were positively correlated with body weight, body mass index, waist circumference, hip circumference, body fat (%) and fat tissue (kg) (p< 0.05). In addition, physical activity is a very important statement for FCQ-T scores. Both men and women, the risk of FCQ-T score who exercised for <600 Met-min/week were greater relative to that of those who exercised for ≥3000 Met-min/week. The results of this study showed that an inverse correlation between a number of nutrients intake and depression duration, antidepressant use or FCQ-T scores.  It also emphasizes the beneficial effects of habitual exercise participation on food cravings. Future research exploring the nutritional status of individuals with depression is warranted.
