Agency Forms Undergoing Paperwork Reduction Act Review

    In accordance with the Paperwork Reduction Act of 1995, the Centers 
for Disease Control and Prevention (CDC) has submitted the information 
collection request titled Heat-related Changes in Cognitive Performance 
to the Office of Management and Budget (OMB) for review and approval. 
CDC previously published a ``Proposed Data Collection Submitted for 
Public Comment and Recommendations'' notice on February 25, 2020 to 
obtain comments from the public and affected agencies. CDC did not 
receive comments related to the previous notice. This

[[Page 51440]]

notice serves to allow an additional 30 days for public and affected 
agency comments.
    CDC will accept all comments for this proposed information 
collection project. The Office of Management and Budget is particularly 
interested in comments that:
    (a) Evaluate whether the proposed collection of information is 
necessary for the proper performance of the functions of the agency, 
including whether the information will have practical utility;
    (b) Evaluate the accuracy of the agencies estimate of the burden of 
the proposed collection of information, including the validity of the 
methodology and assumptions used;
    (c) Enhance the quality, utility, and clarity of the information to 
be collected;
    (d) Minimize the burden of the collection of information on those 
who are to respond, including, through the use of appropriate 
automated, electronic, mechanical, or other technological collection 
techniques or other forms of information technology, e.g., permitting 
electronic submission of responses; and
    (e) Assess information collection costs.
    To request additional information on the proposed project or to

Proposed Project

    Heat-related Changes in Cognitive Performance--New--National 
Institute for Occupational Safety and Health (NIOSH), Centers for 
Disease Control and Prevention (CDC).

Background and Brief Description

    NIOSH, under Public Law 91-173 as amended by Public Law 95 -164 
(Federal Mine Safety and Health Act of 1977), and Public Law 109-236 
(Mine Improvement and New Emergency Response Act of 2006) has the 
responsibility to conduct research to improve working conditions and to 
prevent accidents and occupational diseases in U.S. mines. Heat strain 
is one of these occupational diseases and is an increasing problem 
among many industries, including mining. As mines expand into deeper 
and hotter environments, and as heat waves occur with increasing 
frequency and severity, heat strain among underground and surface 
miners is likely to increase. Not only can heat strain lead to heat 
illness, but studies have demonstrated associations between heat 
exposure and work injuries. Although the underlying mechanism between 
heat exposure and injury is not known, reduced cognitive function is 
likely contributory.
    Despite the increasing importance of heat strain in mining, few 
studies have focused on heat strain among U.S. miners. The few studies 
that are available have demonstrated that miners often exceed a core 
body temperature of 38 [deg]C during work activities, which is above 
the recommended threshold, but more information on frequency, duration, 
and intensity of elevated core body temperatures is needed in order to 
focus future heat strain research to better serve the mining industry.
    In addition to determining the patterns of duration and intensity 
of heat strain among U.S. miners, investigating the additional effects 
of heat strain beyond the risk of heat illness is an important step in 
improving miner health and safety. Studies have demonstrated 
associations between heat stress and cognitive deficits, but 
substantial inter- and intra-individual variability exists in the 
physiologic and cognitive responses to heat exposure. More information 
is needed about the most important factors (e.g., age, sex, chronic 
disease, fitness level, hydration) contributing to individual 
variability as well as interactions between these factors, because 
individual variability likely affects the usefulness of one-size-fits-
all heat stress indices that are currently used in mining. 
Additionally, it is unclear which characteristics of core body 
temperature (e.g., absolute temperature thresholds vs. rising or 
falling temperatures vs rate of temperature change) are most associated 
with cognitive dysfunction. A better understanding of how individual 
variability and core body temperature relate to cognitive deficits 
would assist in developing strategies for screening and monitoring 
miners to mitigate or prevent heat strain. Therefore, this study aims 
to assess the following objectives: (1) Whether a core body temperature 
threshold exists at which cognitive performance begins to decline, (2) 
What factors most contribute to individual variability in cognitive and 
physiologic responses to heat, and (3) What patterns of duration and 
intensity of heat strain are most common among U.S. surface and 
underground miners.
    To study these objectives, a dual-arm field and laboratory study 
will be conducted. The field study will be conducted at surface and 
underground mines. Data will be collected from miners working in warm 
or hot areas of participating mines. Participants will swallow 
temperature pills to measure core body temperature and will wear bio-
harnesses to measure heart rate. Two six-minute assessments will be 
taken during each shift. The assessments include questions on 
sleepiness and work tasks and a Psychomotor Vigilance Test (PVT) to 
assess vigilant attention and reaction time. An initial screening 
questionnaire as well as post-shift questionnaires will be used to 
obtain information on risk factors for heat strain and cognitive 
deficits. The purpose of collecting data at the field sites is to 
evaluate the frequency, duration, and intensity of heat strain by 
monitoring core body temperature and heart rate throughout two complete 
shifts, as well as to assess associations between core body temperature 
and cognitive deficits.
    The laboratory study will be conducted in an environmental chamber, 
in which environmental conditions can be highly controlled. Data will 
be collected from miners, construction workers, and firefighters. These 
three groups were chosen because of their risk of heat exposure and 
their proximity to the NIOSH laboratory where the study will be 
conducted. Participants will perform alternating resistance and aerobic 
exercises followed by brief surveys to evaluate sleepiness (Karolinska 
Sleepiness Scale), affect (Positive and Negative Affect Schedule), and 
fatigue. Following these surveys, two cognitive tests (PVT and N-back, 
which measures vigilance, working memory, and complex tracking) will be 
administered. Testing will occur at room temperature and in hot 
conditions to compare cognitive test results between conditions. 
Participants will swallow temperature pills and wear bio-harnesses to 
enable the collection of real-time core body temperature and heart rate 
data. An initial health screening questionnaire as well as additional 
questionnaires administered prior to each test will be used to ensure 
that participants are able to withstand the physical demands of testing 
and to provide information on factors that affect individual 
variability to heat

[[Page 51441]]

tolerance. Additionally, a physical examination and fingerstick blood 
tests will be used for health screening. The purpose of collecting data 
in the environmental chamber is to compare physiologic and cognitive 
measurements at different core body temperatures to evaluate factors 
contributing to individual variability in cognitive and physiologic 
responses to heat and to evaluate whether core body temperature 
thresholds exist above which cognitive deficits are observed.
    The total estimated burden hours are 103. There are no costs to 
respondents other than their time.
