Summary
Adolescent eating behaviors in Dubai show low fruit and vegetable intake, especially among females. Interventions should consider gender differences and family meal support for better nutrition outcomes.
Area of Science:
- Nutrition Science
- Adolescent Health
- Public Health
Background:
- Healthy eating interventions are crucial for adolescents in the United Arab Emirates.
- Understanding adolescent eating behaviors is key to designing effective interventions.
Purpose of the Study:
- To describe eating behaviors of adolescents in Dubai.
- To identify factors associated with fruit and vegetable intake among these adolescents.
Main Methods:
- Sequential explanatory mixed-methods study.
- Randomly selected 10 Arabic high schools in Dubai; included grades 10-12 students.
- Collected data on self-reported intake, eating behaviors, food availability, and sociodemographics; conducted qualitative interviews with 14 students.
Main Results:
- 620 students participated; 57% were boys; most had medium/high family affluence.
- Only 28% met recommended fruit and vegetable intake; males significantly exceeded females (P < 0.01).
- Lunch was most frequent; breakfast often skipped; high fast food/soft drink consumption; adequate intake linked to lunch frequency, male gender, parental support, and positive family meal perception.
Conclusions:
- Significant gender differences exist in Emirati adolescent eating habits.
- Modern work hours threaten lunch as a primary family meal.
- Targeted, gender-specific interventions are needed for optimal adolescent nutrition outcomes.

25.3K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

01:25Regulation of Water Intake
2.8K
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

01:30Regulation of Food Intake
2.9K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

01:18Cognitive Development During Adolescence
612
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

01:30Mixing Concrete

Concrete mixing ensures a homogenous blend where aggregates are well-coated with cement paste. Concrete mixing is typically done using two main types of mixers: batch and continuous. Batch mixers handle one batch at a time, thoroughly combining materials before discharging and receiving the next batch. In contrast, continuous mixers receive a steady flow of ingredients, mixing them consistently and discharging without interruption. Within batch mixers, tilting drum mixers mix with internal...

01:19Mixing Time
481
The concept of mixing time is significant in producing a uniform concrete mix with the required strength. The mixing period starts once all components are in the mixer. Initially, the mixer is charged with 10% of the water, followed by the consistent addition of solids and then 80% of the water. The remaining water is added later, within the first quarter of the mixing period. The minimum mixing time varies according to the mixer's capacity; for example, mixers with up to 1 cubic yard...
