要旨

Introduction:

Microplastics (MPs) are widespread environmental pollutants with possible neurotoxic effects. Exploring links between plastic use, MP awareness, and cognition is key for assessing public health risks.

Objective:

To examine correlations between plastic consumption, MP awareness and attitudes, and neurocognitive function among Greater Jakarta residents.

Methods:

A cross-sectional survey of 562 adults used a validated e-questionnaire covering plastic usage, MP knowledge, attitudes, risk perception, and cognition via the Ascertain Dementia 8 (AD-8). Analyses included chi-square, t-tests, and logistic regression.

Results:

Suspected cognitive impairment (AD-8 ≥ 2) was observed in 44.5% of respondents. High single-use plastic consumption correlated with worse cognition (p = 0.032), while reusable plastic use showed no association (p = 0.605). Awareness of MPs was relatively low, with 19.4% of respondents having never heard of them. Awareness and knowledge also varied significantly by age (p = 0.007), gender (p = 0.004), and education level (p = 0.027). Positive attitudes and higher risk perception aligned with greater awareness (p < 0.001) but not cognitive scores. Risk perception influenced bottled water use (p = 0.009), with low-risk groups consuming more.

Conclusions:

Frequent single-use plastic consumption is linked to poorer cognition, while MP awareness and risk perception do not directly affect cognitive outcomes. Educational strategies may enhance awareness and reduce exposure.

Cross-Sectional Research

Cross-Sectional Research

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Plastic Behavior

Plastic Behavior

A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Cognition and Behavior

Cognition and Behavior

Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Finding Volume Using Cross-Sectional Area

Finding Volume Using Cross-Sectional Area

For solids whose cross-sectional areas vary in a predictable way, volume can be determined by integrating these areas along an axis perpendicular to the slices. This approach is particularly useful for polyhedral solids, where classical geometric formulas may not be immediately applicable. A tetrahedron provides a clear example of how cross-sectional integration can be applied to a three-dimensional object with continuously changing geometry.Consider a tetrahedron with height h and a base that...

Profile Leveling and Cross Sections

Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...
